"Kill John Lennon": Pet Owners are Finding Out Their Sweet Little Cats & Dogs are Sleeper Agents Using this 'South Park' Clip

A sound clip from an episode from South Park aired in 2010 is going viral on TikTok. It's not your usually Gen-Z trend of people dancing to the sound or giving make-up tutorials to it. Nope. It's them testing out to see if their sweet little innocent pup or kitten is actually a Russian sleeper agent ready to jump into action at any moment the activation sound is played. Turns out that activation sound is this clip from South Park where Butter's is chanting “Kill John Lennon.” The episode was a play on the theory that J.D. Salinger's novel Catcher in the Rye helped instigate the murder of John Lennon.
