You Can't Fix Stupid (but you can negate it with a 2 x 4) plaque
You can't fix stupid, but you can negate it with a 2 x 4 saying on a plaque. Designed in Fusion 360 for fun. The plaque can be hung (put a sticky hanger on the back) or make one of the many stands you can find here on Thingiverse.
Color change for whatever text color you choose is at 2.2mm or layer 11 and to change back to the background or to whatever border color you like is at 3.2mm or layer 16.
