A crazy theory posted online claims that, since 1993, every episode of The Simpsons has been a figment of Homer's imagination.
An article posted on the DailyMail, states that the theory got its start on Reddit.
Reddit user 'Hardtopickaname,' writes that it all started in an episode that aired in October 1992 when Homer is told he only has 6 months to live.
Six months later, in April 1993, Homer falls into a coma after a prank by Bart.
'Hardtopickaname' writes that after that episode, the shows become more outlandish, suggesting they are happening inside Homer's head.
He also say this may explain why the characters never age.
