An assassin who charges $10,000 per shot who never misses goes to a bar, a man whose resting his head on the counter with 3 glasses of beer finds the assassin and says "hey, are you the guy who never misses?"

"Yeah, it'll be 10k for one though"

"Right, I have 20, so my wife and best friend is having an affair and I want you to shoot my wife in the head and blow my friends pecker off"

After the assassin climbs on a roof and waits a couple minutes, the guy says "what's taking you so long?" Then the assassin replies with "I can save you 10 grand right now"
