Overheard on the bus...

Conversation between a small boy and his two uncles:-

Boy: Uncle John, is Uncle Peter your wife?

John: No, he's my husband.

Boy: My mum says you need a woman to have a baby, so how can you have one?

John: We're going to buy one from a big baby shop.

Boy: Can I come too?

John: If you like.

Boy: What are you going to call it?

John: Well, I want Patch and he wants Rover.
