Krusty's secret identity
Have you ever wondered why Homer and Krusty the Clown look so similar?
It turns out that the pair's similar design was intentional, with Matt Groening explaining that he wanted to showcase a son who had no respect for his clown-like father, but was a big fan of a literal clown that resembled him.
He said: "The satirical conceit that I was going for at the time was that 'The Simpsons' was about a kid who had no respect for his father but worshiped a clown who looked exactly like his father."
Matt also revealed that he initially planned to make Krusty Homer's secret identity, though scrapped the idea after deciding it would be too complicated.
