A teenage boy is getting ready to take his girlfriend to prom. First he goes to rent a tux, but there's a long tux line at the shop and it takes forever. Next, he has to get some flowers, so he heads over the the florist and there's a huge flower line there. He waits forever but eventually gets the flowers. Then he heads out to rent a limo. Unfortunately, there's a large limo line at the rental office, but he's patient and gets the job done. Finally, the day of the prom comes. The two are dancing happily and his girlfriend is having a great time. When the song is over, she asks him to get her some punch, so he heads over the the punch table and there is no punch line.
