Michael, who had problems with premature ejaculation, went to a sex shop for a remedy.

The clerk handed him a little yellow can and said, "This is Stay-Hard Spray; put on a little and you can go all night!"

Delighted, Michael took it home, stowed it on the cellar shelf and waited eagerly for bedtime, when he sprayed some on and went upstairs to his wife. However, it seemed to make him spend himself quicker than ever.

The next day he returned to the sex shop, slammed the can down on the counter, and snapped, "This stuff makes me worse than before!"

Upon reading the label, the clerk asked, "Did you hide this stuff on the cellar shelf?"

"Yeah, so?" said the disgruntled customer.

"You must have grabbed the wrong can. This is Easy-Off."
