Joe went into his proctologist's office for a rectal exam.
Elaine, the doctor's new nurse, took him to an examining room and told him to get undressed and have a seat until the doctor could see him.
While waiting, Joe observed that there were three items on a stand next to the exam table:
* a Tube of K-Y jelly
* a rubber glove
* a beer
When the doctor finally came in Joe said, "Look Doc, I'm a little confused. I know what the K-Y is for, and I know what the glove is for, but can you tell me what the BEER is for?"
The doctor flung the door open and yelled to his nurse, "Damn it Elaine, I said a BUTT LIGHT!"
