 * Barney sees a three-eyed monster, which frightens him. He then throws down the bottle of juice and quickly drinks some Duff Beer in order to overcome it. A pink elephant marches through the door to Barney's aid and stomps on the monster. Barney's elephant resembles the pink elephant that Dumbo the elephant (the title character from the animated film ) sees when he mistakenly becomes drunk.

 * It's implied in the end of the flashback that Abe enlisted Homer into the (or at least attempted to enlist him) as punishment for Homer's behavior at Woodstock. Homer, of course, was way too young to enlist, but again, Abe being Abe, that wouldn't have stopped him from trying.
 * When Seth and Munchie talk about the profits from their business, Homer says that must be spinning in his grave. Peter Fonda was still alive when the episode first aired, but (Homer being Homer) it's entirely possible that Homer's self-education in hippie culture didn't include the detail of whether Fonda was still living at the time.
