An old man finds a condom in his grandson's apartment and asks what it is."It's a condom," replies the grandson, sheepishly."What do you use it for?" asks Grandpa.The grandson is embarrassed, so he says, "I use it to keep my cigarettes dry when I smoke in the rain."Grandpa says, "That's a great idea." He goes to the drug store and asks the pharmacist for a condom."What size would you like?" asks the pharmacist."Big enough to fit a Camel."
