- Hello, there. How've you been?
- Hello.
- Say, I met Joe Green just now. He's mighty sore at you.
- I expect he is. We walked out of his show.
- And I don't want to talk about it. Jack, same again.
- OK by me, brother. Give me a scotch, please.
- Come on, you two. We only got five minutes.
- Evening, Jack. What are you going to have, girls?
- Me, too. Three whiskey sours, Jack.
- Oh, look! There's Maxwell Frere the ventriloquist.
- Never seen him. Is that his dummy?
- Yes, Hugo Fitch. Isn't he quaint?
- Oh, I'd just love to pick him up.
- Oh, you can't, Mitzi, the man's plastered.
- You know very well I mean the dummy. You're awful!
- Go ahead, then, why don't you?
- Oh, Mr. Frere, I hope you wouldn't mind, but he looks so cute.
- On your way, sister. On your way!
- Oh, aren't you a little devil? Come along now.
