Before you watch, beware — this bizarre tune will be stuck in your head all day. When a 1976 video featuring Russian singer Eduard Khil surfaced online, the Internet couldn't look away. Khil oddly lip-syncs to the lyric-free song "I Am So Happy to Finally Be Back Home," sporting a creepy facial expression and wooden dance moves. The video's popularity led to a surge in Khil's fame, prompting fans to urge him to tour abroad.
