Condoms and Insecticide

A guy walks into the Pharmacy. He went to the Pharmacist and asked for a tube of insecticide and a box of condoms.

The pharmacist looked at him strangely, and replied, "don't you mean a tube of spermicide?"

The fellow replied "no, insecticide."

The pharmicist couldn't resist and asked, "why is that?"

The fellow replied, "Cause my wife has a bug up her ass, and I'm going after it!"
