A guy is bragging to his poker/drinking buddies that he can fart the national anthem. One of the guys calls his bluff and challenges him to do it. He gets up from the table, drops his pants, bends over, grunts, and drops a huge steaming load of shit on the host's living room floor. The host screams "What the hell!?! You said you were going to fart the national anthem, not shit on my floor!!!" The guy shrugs his shoulders and says "I was just clearing my throat!"
