I read this one recently and thought it was funny.
I was 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!
