Bathroom Stall Dialogue

I was barely in the stall to pee for 5 seconds 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, Not too much!" 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!!!"
