I don’t work on cars, but I do work on machines. Something anyone who works on mechanical things hears a lot is “It’s making a funny sound.”
That doesn’t tell me much, so I tend to ask a few follow-up questions.
“Well, can you be more specific? Is it a THUNK or a SSSKKKKKRREEEEEeeeeeeeeeeeeee?”
“Does it sound like Lynyrd Skynyrd or Flipper? Is it more The Prodigy or Chemical Brothers? Oh… it sounds like Todd Rundgren? That’s nothing to worry about.”
If you really want to freak a mechanic/maintenance person out, just tell us it’s making a strange sound… and it’s just like Nickelback!
Oh Shit! Hit the E-Stop! It’s about to blow!
