The Stupor Salesman Scene

Emery Hawkins handles Daffy Duck selling brass knuckles to Slug McSlug.

I love how Daffy searches through his case of supplies, throwing out a bra in the process. There's a really nice effect of it being in slow-motion, even though it really isn't.

The look of terror on Daffy's face when he's about to get socked is the kind of thing that separates good animation from great.
