- Oh, so you won't talk, eh?

- You want to see me?

- Well, er I rather thought I had an invite from our young friend here.

- After all, Mr. Frere, I'm a ventriloquist myself, you know...

- Hell, I'm soaking.

- There's a clean towel in here.

- What gag? 'Cause I don't quite follow you.

- Well, just now before you came in.

- What did he say?

- Hold on, don't let's start that all over again.
