Buying Condoms

A sixty year old man walks into a big drug store and walks up to the girl
at checkout 3.  He asks her, "Do you have any condoms here?"

She says, "Sure, what size are you?"

"I don't know," he replies.

"Well, let me just check," The cashier says as she unzips his pants and
takes a feel.  She then says over the intercom, "EXTRA LARGE CONDOMS TO
AISLE 3 PLEASE."  They bring them over and the old man pays and leaves.

Then a thirty year old man walks into the store and goes up to checkout 3
and asks, "Do you sell condoms here?"

She replies, "Sure, but what size do you need?"

He says "Well, I don't know."

She says, "Just let me check here," as she unzips his pants and takes a
couple of tugs and says over the intercom, "LARGE CONDOMS TO AISLE 3
PLEASE." they are brought over, the man pays and leaves.

Later that day a sixteen year old guy comes into the store and goes up to
the girl at checkout 3 and asks sheepishly, "Um, ah, do you sell any condoms
here?"

"Yep" the girl replies, "But what size do you need?"

"I don't know," he says.

She unzips his pants for a feel and then says over the intercom,
"CLEAN UP TO AISLE 3 PLEASE."
