There’s an episode where Homer is banned from Moe’s bar. A few scenes after his banning, a guy who looks exactly like Homer in disguise, with a moustache. Moe tells him to give it up and leave.
“Homer? Who is Homer? My name is Guy Incognito!” the man says. Moe and the barflies beat him up and toss him out of the bar - at which point Homer walks past the bar.
Evergreen Terrace is the street the Simpsons live on. Sideshow Bob was once locked up in Morningwood Penitentiary. Fallout Boy is Radioactive Man’s Robin-esque sidekick.
And to show you how obscure some of these reference are, even I didn’t get “Speedholes.” But apparently, in the episode where Homer doubles for Krusty, a car salesman tells Homer that a car has “speed holes” to make it go faster. The car has actually been pumped full of bullets by Mafia hitmen who think Homer is Krusty, who owes them money. Later, Homer uses a pickaxe to install speed holes on his own car.
