I had all four surgically removed when I was 15. Oh, the laughing gas... so much fun, except I went paranoid on the nurses, and was yelling at them to stop, and that they were trying to kill me. Mom could hear me in the waiting room. Talk about embarassing moments...
I had them taken out on a Friday, and ended up having a bad reaction from the codeine at first (vomited quite a bit). On Monday, I was back at school, having finally been able to take the codeine without throwing up, and my algebra 2 teacher was making his rounds, helping as we worked, picked up my paper, and promptly sent me to the nurse. Date on my paper: Jan. xx, 1871. (This was in 1988). I couldn't figure out why he thought that was a problem. The rest of the math problems were... interestingly solved.
Believe it or not, while I was in the nurse's office waiting for my mom, the principal came in and "helpfully" told me all about when he had his wisdom teeth out, and how he was back at work the same day. He couldn't believe that I was still having huge amounts of pain (hence the need for codeine, and being really loopy at school). "You're all a bunch of Whiners!" was his favorite saying.
Anyway, never ended up with any really huge problems after that. Just no fun at the time.
