"I AM THE WALRUS." BtVS Intertext/Allusion.
In "What’s My Line, Part 2" (Season Two) Xander refers to the Beatles lyrically surreal track ‘I am the Walrus’ from the 1967 album Magical Mystery Tour when he describes the Tarakan assassin made of maggots as "I am the bug man, coo coo ca-choo." The actual lyrics are, "I am the eggman/they are the eggmen/I am the walrus/goo goo g' joob."
