A gynecologist notices that a new patient is nervous. While putting on the latex gloves, he asks her if she knows how they make latex gloves. The patient says no. The doctor says: - There is a plant in Mexico full of latex that people of various hand sizes dip their hands into and let them dry. She does not crack a smile, but later she laughs. The doctor says: - What's so funny? She answers: -I'm imagining how they make condoms.
