Frank and Colin in “Unfinished Business”

You know the strangest thing about Mr. Wilson? When he comes over he never says anything.

Yeah, that’s because he is a mute.

Oh right. [Pause.] What’s a mute?

He’s a mute - he can’t talk.

Ohh... No, I’m still not clear on this mute business.

For some reason he is unable to speak.

Ohhh... No, I still don’t get it.

He’s a mute! He’s dumb!

Yeah, well, I’m dumb too, but at least I’m polite enough to speak to people!
