Prom

Billy was going to his high school's prom with his girlfriend Sally on Friday night. So Friday morning he goes to pick up his tuxedo, but there's a really long line and he has to wait 45 minutes to get his tuxedo. Then he has to go get some flowers for Sally, but again there's a long line and he has to wait for an hour to get the flowers. Once he's ready he starts driving to Sally's house to pick her up, but there's a lot of traffic and has to wait again. He finally gets to the dance. After dancing for a little bit with Sally, she gets thirsty and asks for some punch. He goes to get her some, but there's no punch line.
