Simpsons producer Al Jean has debunked fan speculation that Homer has been in a coma since the early Nineties.
Sound bizarre? The theory was first thrown up on Reddit earlier this month, when "Hardtopickaname" suggested that our favourite yellow dad has been a "vegetable for over 20 years", ever since an accident in an April Fools' Day episode.
So It's Come To This: A Simpsons Clip Show aired in 1993 and fans believe every Simpsons adventure since has been in Homer's mind.
Oh, and all those celebrity appearances? They came from Home hearing Marge, Bart and Lisa talk about famous people by his bedside.
The episode involved Bart shaking up a can of Homer's beer with a paint shaker. When Homer opened the can, there was a huge explosion, and next thing we knew he was in a coma for seven weeks after being crushed by a candy machine at the hospital.
