From a golden era season 7 episode 25 entitled “Summer of 4 foot 2” where the Simpsons use Flanders’ beach house, Homer grabs the sticky note from Marge that’s originally attached to the fridge. You can get this as either a sticker or shirt and I’m really hoping you’ll get someone telling you “Well duh” in a Marge voice. Granted that was her response to the sticky notes on the ice tray.

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