Made me think of that scene in the BBC sitcom Faulty Towers with John Cleese:
Mrs. Richards: Are you the manager?

Basil Fawlty: I am the owner, madam.

Mrs. Richards: What?

Basil Fawlty: I am the owner.

Mrs. Richards: I want to speak to the manager.

Basil Fawlty: I am the manager, too.

Mrs. Richards: What?

Basil Fawlty: I am the manager as well.

Manuel: Manajer, he manajer.

[Basil smacks him]

Mrs. Richards: Oh, you're Watt!

Basil Fawlty: I'm the manager!

Mrs. Richards: What?

Basil Fawlty: I'm the manager!

Mrs. Richards: Yes, I know, you've just told me. What's the matter with you?
