Bloke walks into a restaurant with his dog and they both sit at a table.

The manager comes out to protest about the dog being in the restaurant.

Manager: I'm sorry sir, but dogs are not allowed in the restaurant. You have to take him outside.

Bloke: But this dog is very special. He can talk, so he should be allowed to stay inside.

Manager: Oh, how ridiculous...there's no such thing as a talking dog.

Bloke: Well, see for yourself. Why don't you ask him a few questions?

Manager: Ooh, all right then... Now, what's the opposite of smooth?

Dog: RUFF

Manager: What's on the top of a house?

Dog: ROOF

Manager: What's on the outside of a tree?

Dog: BARK

Manager (a bit surprised and flustered): LOOK, I don't care! The answer is NO. You gotta take your dog outside...NOW!

The bloke and his dog stood up to leave and as they were approaching the door, the dog turned around and said,

"Did I get them all right?"
