Billy called little Johnny

One day Billy called little Johnny.

Billy: I’m in big trouble!

JOHNNY: Why is that?

Billy: I saw a mouse in my house!

JOHNNY: Oh, well, all you need to do is use a trap.

Billy: I don’t have one.

JOHNNY: Well then, buy one.

Billy: Can’t afford one.

JOHNNY: I can give you mine if you want.

Billy: That sounds good.

JOHNNY: All you need to do is just use some cheese in order to make the mouse come to the trap.

Billy: I don’t have any cheese.

JOHNNY: Okay then, take a piece of bread and put a bit of oil in it and put it in the trap.

Billy: I don’t have oil.

JOHNNY: Well, then put only a small piece of bread.

Billy: I don’t have bread.

JOHNNY: Then what is the mouse doing in your house!?
