This design comes from an episode called “Fat Man and Little Boy” which is the fifth episode of season 16. Homer essentially lives the dream when he quits his job because his son is making a ton of money. Bart begins designing crude t-shirts and starts selling them in stores owned by Goose Gladwell, who owns stores that sell all sorts of novelty toys. As you can imagine, I’ve got this episode saved as there are a ton of other simple shirt design I plan on recreating.

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