How the Test Was Won/References

Trivia

 * This is the second time that a character discovers(s) has a blemish and upon telling it "Not on my day you don't!" it instantly recedes/recovers (in this case, Homer being hit with a falling flower pot and receiving a bruised bump on his head). The first is when Marge discovered that she had a zit on her lip while preparing for her "third" remarriage (actually second, as Reverend Lovejoy's remarrying Marge and Homer didn't count as his ministering license had expired during that time) in the episode Wedding for Disaster.
 * This is the second episode where a Simpson rides on a garbage barge. The first being Homer the Heretic.

Cultural references
During this episode (at the beginning) Homer remembers most of the times he got injured.
 * When Bart, Nelson, Jimbo, Kearney, Dolph, and Ralph go to the "helicopter", Gonna Fly Now, the theme from Rocky, plays.
 * There is also a Kid vs. Kat episode called How the Test Was Won. However, this is probably a coincidence, since the title card shows it's probably based on the movie How the West was Won.
 * Footloose plays when The principals and the kids begin to dance.
 * Oddly, Homer had a flashback from Treehouse of Horror XIII. However, he could have been exaggerating about lots of Homers falling off the cliff.
 * Homer's premonition of the massive accident in his house (aside from Marge Simpson and Lindsay Naegle making out) is similar to the premonitions seen in the Final Destination franchise.

The episodes he remembers are as follows:
 * Homer at the Bat
 * Bart's Friend Falls in Love
 * Deep Space Homer
 * Homer's Triple Bypass
 * Homer Badman
 * Lost Our Lisa
 * Marge vs. Singles, Seniors, Childless Couples and Teens and Gays
 * Trilogy of Error
 * He Loves to Fly and He D'ohs
 * Dumbbell Indemnity
 * Blame It on Lisa
 * Treehouse of Horror XIII
