But how do they roll them?

A dentist notices that his next patient, an elderly lady, was looking very nervous so he decided to tell her a joke to help her relax. While he was putting on his gloves, he asked,

"Do you know how they make these gloves?"

"No, I don't." She replied.

"Well, there's a building in China with a big tank of latex, and worker of all hand sizes walk up to the tank, dip their hands in, let them dry, peel them off, then put them in the boxes of the right sizes."

She didn't even crack a smile.

"Oh well, I tried," the dentist thought and then he began to work.

About 5 minutes later, the elderly woman began to laugh real hard, making the dentist stop the delicate procedure he was doing.

"What's the matter?" He asked

She stopped laughing and said, "I was just picturing how they make condoms!!"
