So a teenage boy asks a girl out to prom

He asks her out, and he needs to plan, so first, he needs his tuxedo.

So he goes to the tuxedo shop, and there's a huge line of people there, so he waits for 30 minutes, then an hour, and he finally gets his tuxedo.

Then, he needs to rent a limo, to look nice and formal and everything, so he walks into the limo rental shop, and again, there's a huge line, so he waits for 30 minutes and then an hour goes by, then 2, and he finally gets his limo.

On the night of the prom, he pulls up to her house with the limo, and she gets in, and on their way to the prom building, a huge traffic jam happens! So they wait, and then 30 minutes goes by, then an hour, and they finally arrive at the building!

So they walk in, take some pictures, and dance for a bit, and after a while, the girl asks, "hey can you get us some punch?"

So the boy walks over to the punch bowl and guess what?

There's no punchline.
