Question about the New Blockbuster Video Commercial

I’m talking about the spot where the rabbit and the gerbil are watching the Blockbuster across the street when the “reception” starts to go out and the gerbil has to adjust the rabbits ears to clear up the picture.

We see a brief clip of some guy doing a funny walk. I’m guessing it must be an old “Tonight Show” clip from the 60s judging from the curtain in the background. Can anyone identify this performer?
