"Mad Men" got a visit from Mr. Belding (Dennis Haskins) and Rory Gilmore (Alexis Bledel) this week.
On this week's episode of AMC's "Mad Men," we saw the innocent Rory Gilmore (Alexis Bledel) fool around with Pete Campbell, and Mr. Belding (Dennis Haskins) of "Saved By The Bell" fame popped up as a Cool Whip test-kitchen scientist ... with a few added pounds.
The blast from the past got us thinking about other familiar TV faces who have made appearances on the hit AMC series, which keeps its guest stars list a secret.
From Angela Chase's mom on "My So-Called Life" to Alex Mack herself, Larisa Oleynik, click through our slideshow to see which former small screen stars have had stints on "Mad Men."
