“I Love Lucy” Friday: The classic Harpo Marx scene!

This is just some of the most brilliant physical comedy in the history of I Love Lucy.

In today’s clip, Lucille Ball talks to Dick Cavett about doing the classic scene with Harpo Marx where she is dressed like him and tries to convince him he’s looking into a mirror by matching his every move.

What a treat to watch two comedy geniuses go toe to toe.
