Old and New Jokes

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 whats that pop every so often? Oh, its just the same as in the baby-bottle nipple machine, says the guide. It pokes a hole in every fourth condom. Well, that cant be good for the condoms! Yeah, but its great for the baby-bottle nipple business!
