Prom Night

A boy asks his girlfriend to the prom. When she says yes he says
"Since you do so much for me I will take care of everything."
He goes to buy the tickets but it is very busy, so he waits in line, waits in line, waits in line. He finally is able to get the tickets.
He will go get a restaurant reservation next, but his phone is dead so he walks into one hoping to make one that day. The restaurant is packed so he waits in line, waits in line, waits in line. Finally he has a reservation. The next day he goes to rent his Tux, but it is busy that time, so he waits in line, waits in line, waits in line and he finally has his tux.

Fast forward to the prom, his girlfriend asked for him to get her some punch. He goes up to the punch... and there is no punch line.
