Funny Joke

I was in in the public restroom
I was barely sitting down when I heard a voice in the other stall:
"Hi, how are you?"
Me: (embarrassed) "Doin' fine!"
Stall: "So what are you up to?"
Me: "Uhhh, I'm like you, just sitting here."
Stall: "Can I come over?"
Me: (attitude) "No, I'm a little busy right now!!"
Stall: "Listen, I'll have to call you back. There's an idiot in the other stall who keeps answering all my questions!
