10. Lloyd's bladder release beer, Dumb and Dumber (1994)
The Farrelly Brothers and Jim Carrey have made a comfortable living off of gross-out humor, and this scene from Dumb and Dumber might be the team’s best yet.
After Harry and Lloyd hop into their dog van to elude Seabass and his vicious crew, Lloyd suddenly has the urge to pee. Unable to stop driving, he’s forced to relieve himself into some empty beer bottles. When a quick-tempered cop subsequently pulls them over, the officer demands that they hand over what he thinks is an open bottle of alcohol. Unfortunately for him, he's a little too diligent at his job and decides he needs a sip of the “booze” just to make sure. Needless to say, hilarity ensues.
