A guy wants to take his girlfriend to prom

So he waits in line to buy tickets. It's a long line. He wants it to be a memorable night- he stands in line for hours to get a limo. On his way to pick her up, he stops to buy flowers. Theres a long line here too. When they get to the prom later that night, she suggests they get some punch. He goes to the refreshment table and there's no punch line.
