It was a "Cosby Show" reunion on "Late Night With Jimmy Fallon" Friday when Bill Cosby and Tempestt Bledsoe, who played Vanessa Huxtable on the series, sat down on Fallon's couch.

The late night host explained that the "Cosby Show" reunion was a happy coincidence since both guests happened to be booked on the same night. "This is truly surreal for me," Bledsoe said about sitting next to her TV dad after a clip from her show "Guys with Kids" played that featured her talking about sex.

Fallon asked Cosby if it's fun to watch his TV daughter grow up and he replied emphatically, "No!" "When she turns out to be stunning, then you have problems," he explained.

Bledsoe said the two get together often, but Cosby told her not to lie and joked, "Sometimes my checks are late and that's when I see Tempestt."

The entire cast of "The Cosby Show" reunited in 2009 on the set of "Today," 25 years after the series premiered. "The Cosby Show," which ran from 1984 to 1992, followed the Huxtables and their antics at their Brooklyn brownstone.

Many members of the cast are still on TV: Phylicia Rashād (Clair) is about to star on NBC drama "Do No Harm"; Malcolm Jamal-Warner (Theo) stars on BET's "Reed Between the Lines" and makes guest appearances on "Community"; and Keshia Knight Pulliam (Rudy) recently ended her five-year run on "Tyler Perry's House of Payne."

Watch Cosby and Bledsoe's "Cosby Show" reunion on "Late Night With Jimmy Fallon" in the clips above and below:

"Late Night With Jimmy Fallon" airs weekdays at 12:35 a.m. EST on NBC.

  • Joshua Jackson, Michelle Williams & Katie Holmes On "Don't Trust The B---- In Apartment 23"

    While we're very excited to see Busy Philipps and James Van Der Beek back together on the ABC comedy, a "Dawson's Creek" reunion is just not the same with the rest of the gang. Van Der Beek, Jackson and Williams have been teasing a reunion for a while now, but Holmes seemed iffy. However, <a href="http://www.huffingtonpost.com/2012/07/03/katie-holmes-dawsons-creek-reunion-tom-cruise_n_1647000.html" target="_hplink">after her divorce from Tom Cruise, it was reported that he was the one who didn't want the Capeside crew to reconnect</a>. But now that Holmes is a single lady, someone needs to get this started!

  • Christina Applegate On "Modern Family"

    It would be heartwarming to see the "Married With Children" father and daughter reunited on "Modern Family" after all these years. Maybe Applegate could make a cameo as a wacky cousin from Jay's ex-wife's Dede's side of the family.

  • Elizabeth Berkley and Lark Voorhies on "White Collar"

    It's beyond time the ladies of "Saved by the Bell" reunite. Elizabeth Burke's (Tiffani Thiessen) high school friends (Elizabeth Berkley and Lark Voorhies) come calling and need the FBI's help. Good thing Peter and Neal are available.

  • John Stamos On "90210"

    Uncle Jessie and Aunt Becky back together again? Yes please! "90210" could stage a full-blown "Full House" reunion with Lori Loughlin making an appearance. Why not have John Stamos play her new love interest?

  • Sarah Michelle Gellar On "Bones"

    Before Stefan/Elena/Damon, Bill/Sookie/Eric or Edward/Bella, there was Buffy and Angel, the couple who made dating a bloodsucker look glamorous and tragic way before those copycats. Nowadays, David Boreanaz has traded in his fangs for an FBI badge on "Bones," but we'd still like to see SMG swooping in to try and seduce him while Brennan's on the lam, or at least commenting how good he looks with a tan, next season.

  • James Franco On "Cougar Town"

    James Franco is long overdue to reunite with his bad-girl "Freaks And Geeks" co-star Busy Phillips, and Laurie (Busy's character) could use a tall, dark handsome stranger in her life. Let's bring back Daniel and Kim!

  • Tom Hanks On "Girls"

    On the upcoming season of "Girls," "Bosom Buddies" alum Tom Hanks could show up as Hannah's dad's (Peter Scolari) old friend from college who Hannah develops an irrational crush on. Papa Horvath needs his bosom buddy!

  • Max Casella on "How I Met Your Mother"

    "Doogie Howser, M.D." veterans gotta stick together. Max Casella could pop up on "How I Met Your Mother" as a doctor Barney turns to when the threat of an STI rears its ugly head.

  • Jared Leto On "Homeland"

    There's no time like the present for Jordan Catalano to make a comeback, and where better to do it than in his "My So-Called Life" co-star Claire Danes' hit show? Leto can play eccentric pretty well, so we suggest Leto should appear as a fellow psychiatric patient Carrie meets following her ECT therapy -- she already has a great track record with dating unstable guys.

  • Fred Savage On "Sullivan & Son"

    Dan Lauria plays Steve Sullivan's father on the new TBS bar comedy "Sullivan & Son." You know what'd be funny? If Lauria's other TV son, Fred Savage from "The Wonder Years," showed up in a cameo as a drunk, rowdy customer who had to be thrown out of their establishment.

  • Jurnee Smollett on "Baby Daddy"

    It's been a few years, but we bet Michelle Tanner's "Full House" BFFs still keep in touch. Jurnee Smollett could pop up on "Baby Daddy" as Tucker's (Tahj Mowry) old flame. Could it be rekindled?

  • Jaleel White On "Hart Of Dixie"

    Reginald VelJohnson -- the artist formerly known as Carl Winslow from "Family Matters" -- plays Bluebell, AL theatre expert Dash DeWitt on "Hart of Dixie." He runs an arts blog on the town's website, and do you know what every local theatre blog needs? A nerdy intern, preferably played by Jaleel White. Make it happen, CW.

  • Mario Lopez On "Franklin & Bash"

    We think Mario Lopez should take a break from hosting and return to his perfectly permed roots by reuniting with "Saved By The Bell" BFFrenemy Mark-Paul Gosselaar. The erstwhile A.C. Slater could turn up as a client for Gosselaar's Peter Bash, or continue that antagonistic streak by appearing as a law school rival with an ax to grind.

  • Judith Light On "Mistresses"

    Remember the ladies of "Who's the Boss?" Alyssa Milano starred as a housekeeper's (Tony Danza) daughter and Judith Light was the matriarch of the family they lived with and are employed by -- Milano's new series "Mistresses" seems like the perfect opportunity to find a brand new TV reunion around the bend. Light, who recurs on "Law & Order: SVU," could play a legendary famous mistress who helps Milano and the other newbies get through their experiences ... or, she could play the mother of one of the cheating men, who blames it all on his mistress.

  • Kel Mitchell On "Saturday Night Live"

    When "Kenan & Kel" returned to TeenNick and Kenan hosted its opening night on the orange couch, #WheresKel was trending on Twitter. Kenan, an "SNL" cast member, has maintained a steady career after the success of their show and "Good Burger," but we haven't seen much of Kel lately -- he's done a lot of voice work in the past decade and has stuck to the kid market, guest-starring on Disney's "Good Luck Charlie." But maybe it's time for Kel to grow up and reunite with Kenan on "SNL." Will the orange soda jokes translate?
