I took my mother's car into the shop to have a funky noise checked out. It sounded like some sort of cover had come loose and was rubbing up against the front driver's side tire. I couldn't find anything with a quick inspection, so we took it into the shop just in case it was a major problem.
Turns out I was right. A splash cover had come loose under the wheel well and it was grinding up against the tire. So I said to my mechanic:
"So, all I had to do was get all down and dirty and get underneath the car to see the problem."
"You just worry about the professor stuff and let us take care of the car."
