Oh you weren't the only one. It was thanksgiving weekend, with no doc's office open, so we had to go to the emergency room. The receptionist who has to take all of your information started laughing so hard she was crying, then asked if we got it on tape cause we could win $10,000 on funniest home videos. Yes, it did hurt. Knee swelled up to the size of a grape fruit.
It's still funny though. I even laugh about it. Well, I do now, anyway. :-D
