This one teenage guy was getting ready for prom, so he heads over to the store to buy a tux. There's a huge line at the shop, but he's patient and eventually he buys a tux.

Next he goes to get flowers, but upon arriving at the flower shop, there's a large line. But he's patient once again and soon enough, he's paying for the flowers and leaving.

Next he goes to rent a limo, but he finds that there is a massive line. But once more he's patient, and soon he's paying for the rental of the limo.

The night of prom arrives and he and his girlfriend are dancing. The song ends and she asks him to get her some punch, so he goes to the punch bowl, and there's no punch line.

BaBAM

I just did that.

You're welcome.
