There is a great scene in The Big Lebowski. The Dude is tokin' up in his bubble bath, idiot grin on his face. A squad of nihilists bursts through the door of the apartment and into the bathroom. They are pissed, which is quite un-nihilistic of them. They are looking for their money, and have what appears to be a ferret in tow. "Nice marmot." says The Dude, drug-addled. In one smooth motion, the head nihilist releases the rodent from its collar and into The Dude's watery retreat. It's as if a switch has been thrown. The director must have given both the actor and the animal the same instructions, because they both begin to scream and snarl and scratch and thrash as if possessed. What a buzz-kill!

This set-piece scene had me rolling on the floor.
