Other sounds that movies reuse that is like Wilhelm scream?

I'm Canadian. There is a morning weekend radio show where they play a lot of older music and do general 'what's going on' type announcements and such. It's pleasant and sometimes fun and relaxing to listen to on my way to whatever early morning errands are required.

Anyway, Greg from Accounting is a featured co-host, always there.

The thing is.... Greg is a cat. A real cat. (Or rather, a recording of a cat meowing).

And anytime something that might be cat-related or accounting-related comes up, or someone just says "Greg", you hear Greg from Accounting interrupting to yowl in the background.

It's a long-standing cute gimmick that works really well IMO. Never get tired of it.
