A blonde went to the dentist one day to have a tooth pulled and she was very nervous about it. The dentist noticed this and while he was putting his gloves on, he started to talk to the woman so she wouldn't feel so nervous. He asked, "do you know how they make rubber gloves?"
The woman shook her head. The doctor explained, "In a big rubber factory they have a whole lot of men and women with different hand sizes and they have to put their hands into a big huge tank of melted rubber and wait until it dries and then take it off and do it again."
The woman didn't even blink she seemed to be too busy trying not to panic. So he tried telling her a joke or two but once again she didn't even smirk. So he gave up about five to ten minute later.
In the middle of getting the tooth removed she burst out laughing and he had to stop in case she'd choke. He asked, "What's wrong?"
She just laughed and said, "If that's how they make gloves I wonder how they make condoms?"
