This guy had crippling anxiety.

There's this guy who, while growing up, has always been really shy. It was so bad that he never was deathly afraid of being alone with a girl. Finally he found a nice girl that he was going to get married to. He tells his friend his predicament, and his friend says that since he's been married a few years, they'll do a dual ceremony, where the shy guy will get married and the other guy is going to renew his vows. They also get hotel rooms right next to each other. The friend says if the shy guy needs any "help" during the wedding night to just knock on the wall.

Finally the wedding day comes. Each couple goes to their hotel rooms. The shy guy is in the hotel room with his new bride. She goes to the bathroom to slip into something more comfortable. Then he goes to the bathroom to get ready. During this time, the bride gets a feeling that she has to go to the bathroom to do her business. She doesn't want to go back into the bathroom and ruin the moment after she's already "dressed" for the night. So she finds a small box in the room and does her business there. She goes to slide it under the bed but accidentally slides it too far since she slides it right as the shy guy is coming out of the bathroom. It goes under the bed and slides out the other side. They turn the lights off and are about to head into bed. He walks to the other side to get to his side of the bed, but in the darkness he accidentally steps in the box. He screams out, "This box is full of shit!" The friend in the other hotel room then starts hitting the wall and screams back "Turn her over...Turn her over!"
