Mechanic Pranks That Actually Work

Q: Is a left handed screwdriver real?

No. “Left handed screwdriver” is a classic mechanic/trades prank. Screwdrivers don’t work differently for left-handed people—the joke works because it sounds plausible when said confidently. If you want the harmless, laugh-first version, use a realistic prank label and reveal it quickly.

Q: What is blinker fluid?

Blinker fluid is not real. It’s one of the most famous automotive jokes. Often used as a beginner safe prank because it sounds like a real maintenance item. The humor lands when the target realizes it doesn’t exist.

Q: Are muffler bearings real?

No. “Muffler bearings” are a legendary fake part used in mechanic pranks. The name sounds technical enough to be believable for a moment, which is exactly why it works.
