So, do you remember the famous "Who Shot Mr Burns?" cliffhanger that ended season six of The Simpsons in 1995?
You may recall that the person who fired the bullet was none other than toddler, Maggie Simpson - a plot resolution that has irked some Simpsons fans over the past 20 years.
But now Redditor Scarface910 has spotted a blink-and-you'll-miss-it moment in the first part of "Who Shot Mr Burns?" that indicates Maggie was the prime suspect all along.
