Get the You just wouldn't know mug.
Yeah.... That's what I fucking thought to you dumb shit.
Your fiance fuck the mentally disabled?

Nah, man, she wouldn't do that.

Doesn't she know that you would think that?

I don't know.

You DO know, motherfucker. You do know. Why, of all people, would she need to fill in at the easiest house? It's double staffed all ready and it ran with only one person for years; but the only person they could find was someone in a management position? How is that the case? Bet she told you she played board games. That's what they do. Bring them here and tell them "nobody is going to believe you're fucking a retard anyways." Why would they? It's a filthy cripple.

Employee: I caught Debra and Jeff having sex in the office, what the hell are they thinking?

The expression, "I wouldn't piss on him if he was on fire" suggests a very strong hatred for an individual. Often when it is used, someone who hates the person even more comes back with "I wouldn't shit on him if he was on fire", thinking this takes the hate level a step further.

However they are mistaken. Shit, poop or jobbies wouldn't help put the fire out (unlike piss) so in fact by shitting on someone who is on fire you are adding insult to injury, as well as creating a more interesting incident scene for the fire department investigators.

It's important if you are taking a dump on an on-fire person not to let any bits of wee-wee come out as this might put the fire out. Also try to poop from a safe height to avoid charring your back-bottom or your dangly bits/front-bottom. You might also want to try to squeeze it slowly so that the on-fire person can see it coming out and have that as their final vision of life.
Andrew: "That Tony is a complete arsehole: I wouldn't piss on him if he was on fire"

Gary: "Fuck, I wouldn't shit on him if he was on fire"

Andrew: "Actually I would: I'd drop a big chocolate Mr Whippy right on his face. I'd also stuff his pockets with newspaper soaked in gasoline. Bastard."
