In season 11 episode 14 called “Alone again, Natura-diddily” Homer paints his stomach with ketchup as a bullseye in an attempt to get hit with a t-shirt gun. But unfortunately a bobby-pin on the ground catches his eye and he moves out of the way of a flying t-shirt. This leads to Maude Flanders getting hit, falling to her death and killing off her character. If you don’t want to get messy with ketchup you can buy this design instead.

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