Title: Latex factory

A guy is going on a tour of a factory that produces various latex products.At the first stop, he is shown the machine that manufactures baby-bottlenipples. The machine makes a loud "hiss-pop" noise. "The hiss is the rubberbeing injected into the mold," explains the guide. "The popping sound isthe needle poking a hole in the end of the nipple."Later, the tour reaches the part of the factory where condoms aremanufactured. The machine makes a "Hiss. Hiss. Hiss. Hiss-pop" noise. "Waita 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 theguide. "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!"
