My coworker Joe was just looking up someone he knows on eBay, for some reason, and it turns out this person had just bought a mini fridge. But in the same eBay category with mini fridges is another product, which prompted Joe to ask me, "Have you ever heard of a kedger-ator?"

"That's pronounced 'keg-erator,'" I said, "and yes, I have." So I got to explain what one was, and under what circumstances they might be found in the living room of an apartment. (Most of the ones currently for sale on eBay are the smaller ones that can only fit around a pony keg.)
