A new shift manager was being shown around the Latex factor where he was just hired. The plant manufactures various latex products, and has a reputation for using cutting edge technology in their manufacturing process.
On one side of the building, the factory makes baby bottle nipples. The machine makes a loud "hiss-pop" noise, and the shift manager asks his tour guide what it's doing. "As the rubber is being injected into the mould, it makes a hiss noise." he says "The popping sound is from needle poking a hole in the end of the nipple."
On the other side of the building, the two men look at the condom making machine. This machine makes a "hiss.. hiss... hiss-pop" sound during the manufacturing process. "Wait a second," the future shift manager says, "I know what the hiss, hiss is... but what's with the 'pop' noise every once in a while?"
"Oh, that hehe. It's the same as the baby bottle nipple process." says the guide... "It pokes a hole in every third condom."
"But that can't be good for the condoms!" the observant shift manager replied.
"Nah, but it's really good for the baby bottle nipple business!"
