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 condoms here?"

She says, "Sure. What size are you?"

"I don't know," he replies.

"Well, let me just check!"

The cashier unzips his pants and takes a feel.

She then says over the intercom: "EXTRA LARGE CONDOMS TO AISLE 3, PLEASE, EXTRA LARGE CONDOMS TO AISLE 3."

They bring the condoms over, the man pays for them and leaves.

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

The cashier replies, "Sure, but what size do you need?"

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

She says, "Just let me check here."

She unzips his pants and takes a couple of tugs and says on the intercom: "LARGE CONDOMS TO AISLE 3, PLEASE, LARGE CONDOMS TO AISLE 3."

Someone brings the condoms over, the man pays for them and leaves.

Later that day, a sixteen year old boy comes into the store and goes up to the girl at check out 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, CLEAN UP TO AISLE 3!!!"
