A duck walked into a pharmacy, and waddled back to the druggist's counter.

The druggist looked at him and chuckled, "Hey little fella! What can I do
for you?"

The duck says, "I'd like a box of condoms please."

The pharmacist says, "Well, sure! Would you like me to put that on your
bill?"

The duck says, "I'm not that kind of duck!"
