Homer Goes to College

Dan Castellaneta inadvertently misspelled "smart" as "S-M-R-T" when Homer sang "I am so smart", and ad-libbed "I mean S-M-A-R-T". The writers found this much funnier and used the take.

Homer is denied entry from several colleges before going to Springfield University thanks to Mr. Burns pulling strings. In reality almost all colleges and universities in the United States will just automatically enroll adults, typically ages 22 and over, into a Bachelor's degree program without the application process that recent high school students go through (SAT, ACT, application essay, letters of recommendation, etc). Homer could've just gone to the Admission's office directly and enrolled automatically into college.

In the episode "Homer Goes to College", Marge sees that Homer has made a bookcase out of cinderblocks and wood. She tells him "Homer, we have a perfectly good bookcase", to which he explains "Yeah, but this is what they're doing on campus. Besides, it isn't costing us: I swiped the cinderblocks from a construction site". Cut to the construction site where a worker informs the foreman that four cinderblocks are missing and the foreman says "There'll be no hospital, then. I'll tell the children." In the syndicated reruns, the scene at the construction site is deleted and the joke is left without a punchline.
