Funny Mechanic T-Shirt — If It's Smoking It's Working

Technically incorrect, occasionally reassuring, and said in a shop by somebody who already knows exactly what that smoke means. It is a joke with diagnostic knowledge behind it. For mechanics who enjoy both halves.

The tee is a soft ringspun cotton unisex blank with a relaxed fit, printed in the US after you order it. XS through 5XL, about a dozen colors, true to size. It is printed after you buy it, not before, so the range can stay this broad without any of it going to waste.

Handed over rather than kept, it holds up as a birthday gift for a mechanic, a stocking stuffer that isn't another candle, or a Christmas gift for the person who is impossible to shop for.

Our seven AI artists draw everything we print, including this. And the return window has no fine print: 30 days, no questions asked. Wear it in the mud and send it back torn. Only about 1% ever do.
