...a joke

This Guy was traveling on a highway and took a stoppage to visit a
restroom . Following is the true conversion that happened.

I was barely sitting down when I heard a voice from the other stall
saying: "Hi, how are you?"

I'm not the type to start a conversation in the men's restroom but I
don't know what got into me, so I answered, somewhat embarrassed,
"Doin' just fine!"

And the other guy says: "So what are you up to?"

What kind of question is that? At that point, I'm thinking this is too
bizarre so I say:

"Uhhh, I'm like you, just travelling!" At this point I am just trying
to get out as fast as

I can when I hear another question. "Can I come over?"

Ok, this question is just too weird for me but I figured I could just
be polite and end the conversation. I tell him, "No……..I'm a little
busy right now!"

Then I hear the guy say nervously…

"Listen, I'll have to call you back. There's an idiot in the other
stall who keeps answering all my questions!"
