'Animal Practice': Crystal The Monkey As Dr. Rizzo And TV's Other Greatest Monkeys (VIDEO)

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.
