You know when your car starts making a weird sound, and you have no idea what the sound means, but you know it's probably not good? And then you take your car to a mechanic, and you try to describe that sound? This picture posted on Reddit by a user with the handle kylet2272 is a pretty good example of someone's attempt to describe the sound to the repair desk without having an actual recording of it.
In the description field of the repair center's work ticket, the customer service representative wrote, apparently word-for-word, how the customer described the sound. It reads, "Check rattle noise like 2 skeletons making out on a tin roof during a hail storm using a tin can for a condom."
True, skeletons just making out wouldn't necessarily need a condom, but as a Redditor named UselessGadget so astutely commented, "Being they are skeletons, any touching would be considered boning." BOOM, nailed it.
