"Rubber Gloves" joke
A dentist was preparing to clean an elderly woman's teeth. Noticing that she appeared to be a little nervous, he began to tell her a story while he was putting on his rubber gloves.
"Do you know how these rubber gloves are made?" he asked.
"No I don't," she replied.
"Down in Mexico there is a big building set up with a large tank of latex," he spoofed. "The workers there are all picked according to hand size. Each worker goes up to the tank, dips their hands in and then walk around for a bit while the latex sets and dries right onto their hands. Then they peel off the gloves and deposit them in the big 'Finished Goods Crate' and begin the process all over again."
The woman didn't laugh at all! Five minutes into the cleaning procedure, the dentist had to stop because she burst out laughing.
"Oh my," the blushing woman exclaimed, "I just suddenly thought about how they must make condoms!"
