Matt Groening had this self insert character. He kept trying to shoehorn into the show. Believe it or not, that is how Matt Groening sees himself. He wanted him to be good friends with Bart and replace Millhouse. The writers and the studio were concerned about how this would alter the show. And the design was too creepy. Because he looks naked. Matt Groening would always say, that he just has long yellow hair and he isn't actually naked. He wanted him to live in Bart's treehouse and work at the nuclear power plant. Or maybe just hang out at Moes. He wanted this character to be versatile and he could help any characters with their problems.
He pitched this one idea where he would help Lisa win a Jazz contest. Apparently, Matt Groening really regrets not playing the drums in high school and wanted his self insert to be really good at drums. So his character would play the drums in Lisa's Jazz band and they would win.
The writers would call this character Weird Matt. When Groening learned about this he made them change its name to Yellow Matt. The thing is I don't think he ever gave it a name. So they only ever had a place holder.
The thing is if Matt really wanted to he could have pushed this idea through, but after no one wanted it or liked it he gave up and scrapped the whole idea. There is still some art and notes referring to the character floating around.
Matt Groening is very embarrassed about this character. If you ever see him do not bring up "Weird Matt" or "Yellow Matt".
