Peterborough Jokes

Leaving Peterborough for London on a day trip, I decide to make a stop at one of those rest areas on the side of the road. I go in the washroom. The first stall was taken so I went in the second stall. I just sat down when I hear a voice from the next stall... "Hi there, how is it going?" Okay, I am not the type to strike conversations with strangers in washrooms on the side of the road. I didn't know what to say so finally I say: "Not bad..." Then the voice says: "So, what are you doing?" I am starting to find that a bit weird, but I say: "Well, I'm going to London..." Then I hear the person say all flustered: "Look I'll call you back, every time I ask you a question this idiot in the next stall keeps answering me."
