Toilet Conversation Joke

The other day I went into a restroom after having lunch in a restaurant. The first stall was occupied, so I went into the second one. I was no sooner seated than I heard a voice from the next stall, "Hi. How are you doing?"

Well, I am not the type to chat with strangers in restrooms, and I really don't know what possessed me, but anyway, I answered, a little embarrassed, "Not bad."

Then the stranger said, "So, what are you up to?" Talk about your dumb questions! I was really beginning to think this was too weird, so I said, "Well, just like you I came in for some lunch."

Then, I heard the stranger, all upset, say, "Look, I'll call you back later. There's some idiot in the next stall answering all the questions I am asking you!"
