Beware of static cling

My friend took his wife to one of those restaurants where they cook the food right at your table.
It was warm so he took off his sweatshirt.
They enjoyed the meal but when it was time to go he picked up his sweatshirt and something fell on the floor.
It turned out to be his wife's panties. Must've come out of the dryer sticking to the sweatshirt and he never noticed it when he got dressed to go out.
