The biggest star on TV isn't even human!

Crystal the Monkey who plays Dr. Rizzo, Justin Kirk's aid, on NBC's new comedy, "Animal Practice" (previews Sunday, August 12 at 10:38 p.m. ET) is easily the fall's biggest breakout star, as deemed by HuffPost TV's Maggie Furlong. According to TV Guide Magazine, Crystal is raking in $12,000 an episode.

However, Crystal is far from the first great monkey on TV (but may be the most versatile, considering she stars on another NBC show). From Mojo Jojo on "Powerpuff Girls" to Marcel on "Friends," take a look at clips of the best TV monkeys.

  • "Animal Practice," Dr. Rizzo

    Crystal the Monkey is a two-timer on this list with her newest role as Dr. Rizzo on the Fall 2012 NBC comedy, <a href="" target="_hplink">"Animal Practice," which stars Justin Kirk ... but really, more so Crystal</a>. The cute capuchin is the biggest star of the season. Watch Crystal in an adorable plastic visor, taking bets on a turtle race in the back room.

  • "Powerpuff Girls," Mojo Jojo

    Townsville's biggest villain, Mojo Jojo was definitely scary for kids. We love him from his catchphrase ("Curses!") to his outfit.

  • "Friends," Marcel

    Ross' pet monkey Marcel made us laugh a lot -- and cry a lot when he moved on to bigger and better things (like a Jean-Claude Van Damme movie). Not making him a regular cast member was totally a mistake.

  • "Family Guy," Evil Monkey

    Stare, point, cue the creepy music. "Family Guy's" evil monkey hilariously lives in Chris' closet, appearing on the comedy when we feel like we've forgotten about him.

  • "30 Rock," Little Jenna

    Things at "TGS" are usually crazy, but they were escalated to another level of comedy when Tracy skipped rehearsal, putting a gibbon named Little Jenna in his place to prove the staff treated him like a monkey.

  • "Community," Annie's Boobs

    TV star Crystal the Monkey wreaked havoc in her guest appearance on "Community." On the show, she plays Annie's Boobs, Troy's pet monkey who was given to him as a thank you for his work as the bagman in the Chicken Fingers distribution network. Here, watch Annie's Boobs in a hilarious chase from Senor Chang.

  • "The Great Grape Ape Show," Grape Ape

    It's cruel that "Grape Ape's" show was cancelled in the '70s. He was a staple of Saturday morning cartoons.

  • "Full House," Ginger

    When a chimp named Ginger visited the cast of "Full House," she bonded with Michelle (Mary-Kate and Ashley Olsen). Though the Tanner's home was enough of a zoo already, <a href="" target="_hplink">Ginger came into Uncle Jesse's (John Stamos)</a> room and had quite the surprise for him.

  • "Pippi Longstocking," Mr. Nilsson

    As one of Pippi's two pets, Mr. Nilsson was one of our favorite animated monkeys on TV.

  • "Silver Spoons," Harry

    Things got primitive on "Silver Spoons" when Ricky Stratton (Ricky Schroder) decided he wouldn't be living the good life without his own orangutan.

  • "The Magilla Gorilla Show," Magilla Gorilla

    Magilla Gorilla starred in his own show named after himself. What a diva.

  • "Veronica Mars," Oscar

    Kristen Bell tried to save a monkey on "Veronica Mars" Season 3. If only the script had also included a <a href="" target="_hplink">sloth</a>.

  • "Harry's Law," Wentworth Beaumont III

    While Harry (Kathy Bates) and Tommy (Christopher McDonald) are duck hunting, they discovered that the owner of the hunting preserve has been secretly housing a gorilla that's escaped from the zoo on an episode of the late "Harry's Law." Swayed by the Wentworth Beaumont III (aka Wenty's) incredible intelligence (he can use an iPad and knows sign language) and gentle demeanor, Harry agreed to help her get legal guardianship.

  • Mr. Teeny/Mojo/Typewriter Monkeys, "The Simpsons"

    "The Simpsons" has had no shortage of monkey -- there's Krusty's sidekick Mr. Teeny; <a href="" target="_hplink">Mojo, the monkey Homer gets to help him</a> after learning Apu has gotten one when a robbery at the Kwik-E-Mart left him in a wheelchair; and of course, the 1,000 monkeys at typewriters Montgomery Burns has in a room (here).

  • "B.J. and the Bear," Bear the Chimpanzee

    The early '80s comedy starred Greg Evigan as B.J. (Billie Joe) McKay, a professional freelance itinerant trucker who traveled the country's highways with his pet chimpanzee, Bear (named after Bear Bryant, the famous Alabama football coach due to his choice of headwear).

  • "The Monkees"

    We didn't think it would be right to have a list of TV's best monkeys without including "The Monkees." They totally count.

"Animal Practice" previews its pilot episode on Sunday, August 12 at 10:38 p.m. ET on NBC. The series officially premieres with Crystal the Monkey on Wednesday, Sept. 26, 8 p.m. ET on NBC.
