Funny Strange Discussion

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 traveling!"

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!!!"
