A friend of mine is always sending me email jokes. Here's some I found mildly amusing:

The Doctor

A doctor walked into a bank. Preparing to endorse a check, he pulled a rectal thermometer out of his shirt pocket and tried to 'write' with it. Realizing his mistake, he looked at the thermometer with annoyance and said, "Well that's great, just great… some asshole's got my pen."

Police Toilet

Did you hear that someone broke into our local police station and stole the toilet?

Right now the cops have nothing to go on.

Google?

Rings

Two men are sitting in the doctor's office. The one looks at the other one and says, "What are you here for?" The man replied, "I have a red ring around my pecker, what are you here for?" The other man said, "I have a green ring around my pecker." The doctor called the man with the red ring first in his office and examined him. As he was walking out, he told the other guy it was no problem.

The doctor called the man in with the green ring around his pecker and examined him. The doctor says, "Your pecker is gonna fall off and you are gonna die". The mans says, "What?? You told the man with the red ring he was ok, but I'm gonna die??" The doctor said, "Yes, but there's a lot of difference between lipstick and gangrene!"
