When Sam put handcuffs on Luke, he didn't realize that the keys were not in his room. Larry had borrowed his car and the keys were on that ring.
Sam had to go get them but I refused to let Luke ride along in the truck all handcuffed up! To pass the time and to take his mind off his uncomfortable predicament, he and John played a game. Look at how he handles his controller!
I think it was about an hour all told that he was stuck!
Next on the schedule was to give Sam a Swirlie. That is to say, stick his head in the toilet and flush!
