Cross Over: Hank Hill from King of the Hill shows up when Springfield plays against Arlen, drawn in their native way, instead of being Simpsonized (though the promos did have the King of the Hill cast with yellow skin). Hank's family and friends Peggy and Bobby, Luanne, Bill Dauterive, Dale Gribble and Boomhauer also appear, but they don't speak.
Hank: We drove 2000 miles for this?
Fun with Acronyms: The store clerk asking Marge to spell "cup". "C-U-P. I wanna C-U—Oh, my God!"
In the flashback of Homer's gymnastic routine, we get two:
Teenage Lenny wearing a T-shirt that reads, "Bull-Shirt." Take out the "r" in "Shirt" and you got it.
Teenage Smithers' line, "Now, let's bring on the men," given the later episodes heavily hinting that he's a homosexual (and not just an overly sycophantic Yes-Man who has a crush on his boss).
Hypocritical Humor: When Bart was declared fat, Homer called him a disgrace to their family.
Let's See YOU Do Better: In retaliation for Homer's constant criticizing of his job as peewee football coach, Flanders made him the new coach, prompting a scared Homer to say Flanders was doing a good job.
Oh Crap: Homer when he realized Flanders wouldn't let him keep the teasing.
Overly Narrow Superlative: Homer claimed Flanders was the worst coach Springfield's peewee football team ever had. Flanders was the only coach they ever had.
