Here we are at Shout, where audience participation is not only encouraged, it's basically required. Up to the stage here went all the birthday girls, who had to play along with the song "Head, Shoulders Knees and Toes" and touch the appropriate parts...except the piano guys quickly changed it to "Head, Shoulders Boobs and Buns". The ladies got to choose any guy to come up on stage with her. The one in the middle chose the old guy in the hawaiian shirt. When the guys got up, the song changed again to "Head, Shoulders Sack and Crack". Old dude played along really well, and didn't hesitate once to grab his sack in front of 150 people.
