As Pinky and The Brain try to take over their world through yet another crazy plan, they cross paths with, you guessed it, The Beatles (or, in this case, The Feebles).

By the way, The Beatles actually did visit the Maharishi back in 1967 to have some Transcendental Meditation. So yeah, this episode did have its share of references that the kiddie audience wouldn't have understood. As for the song, it's "All You Need Is Love".
