* * 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-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 the 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 "Hiss. Hiss. Hiss. Hiss-pop " noise. "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! "
