Gasman is out at the bar drinking with his buddies all night. Near the end of the evening, he throws up all over his brand new shirt.
"Shit," he says, "my wife is going to kill me! Not only did she buy me this shirt but I told her I'd come straight home from work tonight."
"No problem," says his buddy BFL, "Just hand her 40 bucks and tell her that some drunk threw up on you and gave you the 40 to make up for it. She can't be pissed at you for the shirt and it will explain why you smell like booze."
So Gasman goes home to his wife.
"Honey, I just want you to know this isn't my barf. A sick coworker puked on me and gave me this 40 to replace this shirt."
Gasman takes the money out of his pocket and hands it to her.
His wife looks at him and says, "There's 80 dollars here?"
"Oh I forgot. He also shit in my pants."
