Ace Ventura: Pet Detective was the 1994 box-office hit that turned comedy maniac Jim Carrey into Hollywood's first $20-million man. This gag-filled no-brainer stars Carrey as the titular rubber-faced gumshoe who tracks down lost pets for his heartbroken clients. Ace's latest case involves the apparent kidnapping of the Miami Dolphins' team mascot, Snowflake the dolphin (natch), and his investigation is a source of constant irritation for Miami police lieutenant Lois Einhorn (Sean Young). Friends fans will appreciate the presence of Courtney Cox, who remains admirably straight-faced as the Dolphins' publicist and Ace's would-be girlfriend, but of course it's Carrey who steals the show with shameless abandon. --Jeff Shannon

In When Nature Calls, the inevitable sequel, the disappearance of a rare African white bat, draws Ace (Carrey again) out of his spiritual retreat at a Tibetan monastery following the tragic outcome of his previous case. That traumatic experience, which makes for a hilarious opening-scene send-up of the Stallone thriller Cliffhanger, prompts Ace to venture to Africa, where he goes native with the tribe that hired him to find their symbolic bat. From that point anything goes, with Carrey pushing the boundaries of good taste (what, you were expecting good taste?) up to and including his now-infamous "birth" scene from the backside of a mechanical rhinoceros. Lighten up, and don't be ashamed if you find yourself laughing. --Jeff Shannon
