The visit to the doctors
 

An elderley couple visit the doctors surgery, as the old guy is feeling a bit off colour, and not sure why.
The doctor says to the old guy..."I will need a sample of your urine, your semen, and your excrement"
The old chap being hard of hearing turns to his wife and says "What did he say dear"?
She replies..."HE SAYS HE WANTS TO BORROW YOUR UNDERPANTS"!!!!!

there is nothing funny about soiling my underpants, er um...nevermind, have a great day

joke sounds like it was written by a british guy:)

Heard it b4, but it's still funny
