I was driving along the interstate when I decided to stop at a comfort station.

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 highway comfort stations, and I really don't know quite 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'm driving east."

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!"
