A man walks into a pharmacy and wanders up and down the aisles.
The sales girl notices him and asks if she can help him.
He answers that he looking for a box of tampons for his wife.
She directs down the correct aisle.
A few minutes later, he deposits a huge bag of cotton balls
on the counter.

She says, confused, " Sir, I thought you were looking for tampons for your wife ? "
" You see it's like this.
Yesterday, I sent my wife to the store to get me a carton of Cigarettes
and she came home with a tin of tobacco and some rolling paper.
So, I figure it out, if I have to roll on my own.
SO DOES SHE ! "
