A Crazy Boy in The Toilet Did Something that everybody was Shocked!

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!
