A video for the song “Sweep the Leg” by No More Kings. It not only has the guy who played Johnny but also a Ralph Macchio cameo and lyrics like:

I heard the devil whisper in my ear
He made his message clear
When he said
Sweep the leg, Johnny

There is no fear in this dojo
I was a superhero
King of 1985
I showed no mercy
I was always Cobra-Kai
But I caught a crane kick to the face…

Christ how can this not be one of the funniest songs and videos ever?

Thank you K-Foo for showing me this!
