Last year I graduated from dentistry school. br But no amount of education can change a fool. br My time as a dentist was very brief. br A man came to me and asked me to pull one of his teeth. br I wasn't sure which tooth to pull so I pulled them all. br When he came to, he beat me so bad that I couldn't walk, I had to crawl. br That was the one and only customer I had. br When it comes to dentistry, I'm pretty bad.
