The Cutting Humor of Who Framed Roger Rabbit (1988)

Smartass and Greasy intimidate Eddie Valiant. Toonblades have advantages over their real-life counterparts: they can open in a single frame, and the blade can be longer than the handle. In the hands (paws, whatever) of a maniacal weasel, these bits of ink become formidable weapons.

Greasy flicks open his knife, in preparation for dropping a ton of bricks on Roger.

Smartass spins his knife before opening it. Fortunately, he is foiled before he can file Eddie's probate.
