Funny Joke

one night in a bar a man walked up to the barman and said "you see that glass in the other end of the bar? I bet you $100 I can piss in it from here." the barman says "you're on !" so the guy starts to piss everywhere on everyone even the barman, exept for the glass. "Ha!" says the barman. "you owe me $100" so the guy says "wait here." and he walks to a pool table and gets money from someone and they laugh. "here it is" the man says. "thanks. By the way, why did you two laugh ? you lost the bet" "oh" says the man. "I bet him $1000 i could piss everywhere in the bar and even on you and you'd still be smiling"
