One hot summer afternoon a woman is at the local public swimming pool when she notices a man smoking a cigarette underwater.
She is astounded that such a thing can be so she asks him how he does it.
"It's easy." He said. "I just use a condom."
"Where can I get them?" The woman asked.
"Just go into any drugstore and ask for them." The man tells her.
The next day she goes into her local drugstore and asks the clerk for a condom.
"Any particular kind?" He asks.
"Yes," she replied. "One that will fit a Camel."
