A guy asks a girl to prom...

She says yes,
In preparation, the guy goes to rent a nice suit. He waits in line for a very long time but eventually he gets it.
He decides he wants to be a little fancy and so he goes to rent a limo. There's a large line at the dealer. He waits in line for a very long time but eventually he rents the limo.
On the day of the prom, he gets in the limo and begins to drive to the house of his date. There's a lot of traffic so he waits in line for a very long time but eventually he gets there.
He picks up his date and gets to prom without a problem. They dance, have fun etc.
Eventually the girl gets thirsty and she asks the guy to go get some drinks.
He walks to the punch table and there's no punch line.
