One of the greatest things about animated shows like The Simpsons is that there can be so many jokes stuffed into each episode. The Simpsons is the pinnacle when it comes to nonstop sight gags, especially in the form of signs that appear in the backgrounds of scenes. One Twitter user asked people to share their favorite sign that has appeared on The Simpsons in the over 20-year run of the show, and oh man, they delivered. Get ready to giggle!
