Drunk guy at a bar

So there’s a drunk guy at a bar and all of a sudden he starts to vomit. “Oh no, I vomited on my t-shirt, my wife is gonna kill me!” Says the drunkard. “Let me help you with that”, says the bartender. The bartender goes to the drunk guy and says: tell your wife some idiot vomited on your t-shirt and gave you 10 dollar for the inconvenience. Off he goes, the drunk guy.. he tells his wife the story and hands her 20 dollar. “But you said 10 dollar”, replies his wife. “Yes but the idiot also shat in my pants!”
