This joke is far better than anything else I've seen in this thread:
I guy goes to a party. He's not the 'social' kind of guy, but he really wanted to impress a girl. That being said, he did his best to dress up to the occasion (as suitable for a college party), and "borrowed" his dad's Ferrari to drive up to the house where the party is taking place. Inside, there's far too many people. Each room is barely navigable, but he manages to find his way to a clearing in the crowd. The guy running the party isn't quite the guy you'd expect to throw a party. He's OCD and a control freak, so he's doing everything he can to maintain order-primarily by keeping every single food and drink item separate from each other. Each item has a line; a line for wings, a line for chips, a line for soda...As the party progresses, the lines wax and wane, and our character finds a nice quiet couch where a couple is watching TV. It's set to an all day marathon of professional wrestling. He could care less about what's on, though. He's just looking for an excuse to fill time while he's at the party. After about an hour, someone breaks open the beer, and he doesn't hesitate to grab a few. Normally, he's careful with his alcohol consumption, but the girl still hasn't shown up. Another hour goes by, and he finally catches a glimpse of the girl heading towards the door. He quickly gets up and runs to her, only to see her leaving with one of her ex-boyfriends. In a half-drunken stupor, he cries out, "I was only trying to impress you!" She looked at him, smelled the alcohol on his breath, and replied, "Oh, the social irony!" She turned and left with her man, and he returned to the couch. The professional wrestling marathon continued, as did his alcohol consumption. Soon after, he realized that he would have to drive his dad's Ferrari home. He needed to sober up right away, so in his drunkenness, he decided that he should vomit up the beer as quickly as possible. He needed to find the bathroom, but the house was far too crowded to tell where anything was...So he ran to the back of each and every line, asking "is this the line to the bathroom?" Each time, he got a reply like, "no, this is the line to the karaoke machine," or "this is the line to the assorted vegetable tray." When finally, he came to the back of a line and repeated, "is this the line to the bathroom?" The man promptly responded, "No! This is the punch line!"
