In the 1994 film Ace Ventura: When Nature Calls, Jim Carrey must escape his robotic rhinoceros by squeezing out of its butt while naked.
The prop is quite sophisticated. You can see Adam Savage's complete walk-through of the mechanism and how it functioned to create the scene here.
I'm sure that you're already imagining how enjoyable it would be to own the prop and to role-play the scene yourself on a daily basis. Well, then, good news! The Propstore in Los Angeles is auctioning it soon. The starting price is $2,000, but it's clearly worth more given its obvious office workplace applications.
