Randy Johnson - I'm a dumb dentist

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