Nature's Call

I was traveling back to my hometown and, responding to Mother Nature, decided to stop at one of those rest areas on the side of the road. I went into the washroom. The first stall was taken, so I went into the second stall. I had just sat down when I heard a voice from the other stall. "Hi there, how is it going?" I am not the type to strike up conversations with strangers while sitting on the john in restrooms on the side of the road. I didn't know what to do, but finally I said, "Not bad." Then the voice said, "So, what are you doing?" At this point, I was starting to find the situation a bit weird, but I said, "Well, I'm headed back east." Then I heard the person, all flustered, say, "Look, I'll call you back. Every time I ask you a question, the idiot in the next stall keeps answering me!!!"
