These aren't fan art. These shirts actually appeared in Married... with Children — worn on screen by the cast across some of the most memorable episodes in the show's 11-season run.

Verified episode references for every design:
Jim Jupiter (S4E2), Bundyland (S4E23), No Ma'am (S8E9), Polk High 33 (all 11 seasons), Burned Beyond Recognition (S8E21), Chocolate: It's Not Just For Breakfast Anymore (S8E21), and more.

If you watched the show closely enough to catch these, you already know exactly what these mean. 
Ships worldwide. Officially the most episode-accurate Married with Children merchandise available.
