This design comes episode 17 episode 12 called “My Fair Laddy” where Lisa attempts to make Groundskeeper Willie a proper gentlemen for the school science fair. The side plot is Homer ruining his favourite blue pants and helping the manufacturer raise sales. He does this buy putting some “superliminal” advertising on the back of his head. I don’t recommend doing this so I made a design you can wear to advertise them.

Here’s the link to the product as a pin, but you can view the design on multiple items if you’re interested.
