Programmer Humor

"Get me some oil so I can tap this tight hole. You're going to need to screw it hard, and then drop a double nut on it. Make sure to keep your bush clean, or you can try sticking your finger in and twisting it around, otherwise you'll never get this hard shaft into it. And remember: if it's walking funny when you drill, try putting the tip between a pair of nuts."

Maybe a bit more machining, but it's not even a stretch to make it sound absolutely terrible. Those are all even pretty reasonable statements in context (if you know zero slang), not just isolated words.
