A fellow is going on a tour of a factory that produces various latex products. At the first stop, he`s shown the machine that manufactures baby-bottle nipples. The machine makes a loud hiss-pop! noise.
“The hiss is the rubber being injected into the mold,” explains the guide. “The popping sound is a needle poking a hole in the end of the nipple.”
Later, the tour reaches the part of the factory where condoms are manufactured. The machine makes a noise: `Hiss. Hiss. Hiss. Hiss-pop!`
“Wait a minute!” says the man taking the tour. “I understand what the `hiss, hiss,` is, but what`s that `pop!` every so often?”
“Oh, it`s just the same as in the baby-bottle nipple machine,” says the guide. “It pokes a hole in every fourth condom.”
“Well, that can`t be good for the condoms!”
“Yeah, but it`s great for the baby-bottle nipple business!”
