Stinky and Arnold in “Unfinished Business”

I still can't understand how Lila could prefer your plain, homely, dull as dirt Cousin Arnie over you, Arnold. I mean, you're no Dapper Dan, but you sure are better looking than Arnie. And you're sure a lot more fun to talk to, but she does like him better! Look at her glow!

[mad] Stinky, shut up.

[confused] What'd I say?
