(In a restaurant Guy #1 just returned from using the washroom.)
Guy #1: Hey man, you haven't taken a piss here, have you?
Guy #2: No, but I haven't drained the main vein recently. I think it's about time I go.
Guy #1: Yeah you really should. I was quite impressed with that van Gogh they have on display! (snickering...)
Guy #2 hesitantly: Aww man, you didn't.....
Guy #1: Yeah I did! Our waiter was a total douche. I didn't even get offered a refill.
Guy #2: Y'know what, I thought I had to pee...... but let's just casually get the fuck outta dodge, it can wait.
Guy #1: I hope our waiter has to clean it....... hahahah!
