Two nuns were behind their convent one afternoon, smoking cigarettes.

One nun said, Its bad enough that we have to sneak out here to smoke, but its an even bigger problem trying to get rid of the cigarette butts without Mother Superior finding them.

The second nun replied, Ive found a marvelous solution. Its called a condom. You open the package, take out the condom, put the cigarette butt inside, roll it up, and throw it away later.

The first nun was impressed.

Where can I get these condoms? she asked.

You can buy them at a drugstore, the second nun replied. Just ask the pharmacist.

The next day, the nun went to a drugstore and walked up to the counter.

Good morning, Sister, said the pharmacist. How can I help you today?

Id like some condoms, please, said the nun.

The pharmacist was a little taken aback, but quickly recovered.

Of course, Sister. How many boxes would you like? There are twelve in each box.

Ill take six boxes, said the nun. That should last about a week.

By now, the pharmacist was completely bewildered.

Still, he maintained his professionalism and asked,

Sister, what size would you like? We have regular, large, and extra-large.

The nun thought for a moment and then replied,

Im not really sure. Could you recommend a size that would fit a Camel?

He fainted.
