If your in the right company sarcasm humour Its about throwing it back to each other without taking offence, this is with friends who dont care and no that the best sarcastic put down will win. You have to take what you give or it don't work, if someone out jokes you get thinking quick, don't ever throw a sulk or your crap. never ever try it with a stranger, a TYPICAL sarcastic joke is, I see your not 2 faced or you wouldn't be wearing that one
