Thanks Ted Boucher for pointing out the Burns thing I cant believ I missed that....
Let me focus on season 8 shall we were it is strongly argued that Monty Burns is at his strongest strength compared to other seasons
During an opening couch scene of one such episode it is a direct parody of the previoulsy mentioned album cover, being very closly similar to the animation of it as scene in "The Making of Sgt. Pepper"
It is during this season too that Homer takes his trip after eatting Wax (need I say that several characters in the album cover are wax figures) On this trip lyrics from the Beatles son "I am a Walrus" are quoted
Also some believe that Barney's belch during the "trip" is a reference to the final chord in "A Day in the Life"

However my main point of season 8 is that the PYRAMID Homer climbs to see the coyote looks exactly like the one in "Yellow Submarine" now, maybe we to might need to climb the pyramid (previously stated by many as a field piece)

edit: Also I just had pointed out to me (thank you Justin) that in Season 12 (FIRST began in 1992 and this clue came out 12 years later) the Beatles make a cameo dressed in their Sgt. Peppers garb to recruit teens to join the army a.k.a. ALLIANCE!
