I Take Pleasure In Other People's Pain

I know I am not the only one to feel this way, but when someone hurts themselves, I can't help but laugh. At first, I try to conceal my laughter, but once I find out they are okay and it's just temporary pain, I can't help but bust up laughing. I used to think there was something wrong with me, but I have since learned that a lot of people laugh at others misfortunes. I know I get laughed at when I hurt myself. I was sent this video via e-mail a little while ago, and it made me laugh the first time I saw it, but I was told to watch it a few times and after about three views I was practically rolling on the floor. Her noises are just too funny.....
