29. 10Deep "Problem Solvers"

Released: 2002

This t-shirt started as an inside joke pertaining to the use of violence to solve problems. The tee took off as people got the joke (or didn't), and the success of the shirt brought about many incarnations of the tee and led to the familiar brass knuckle becoming the logo for the brand.

YOU AUGHTA KNOW:
The brand eventually did a women's version of the T-shirt.
