A old man finds a protection

An old man finds a protection in his grandson’s apartment and asks what it is.

“It’s a protection,” 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 protection.

“What size would you like?” asks the pharmacist.

“Big enough to fit a Camel.”
