There is a classic clip where Ed McMahon is drunk on the Tonight Show starring Johnny Carson.  You know Ed was known to have a few. Oh those were the days.  No one will ever be as funny as Johnny Carson, he was and will always be the King of late night.

I remember as a kid, my bedroom was just off the living room.  My Grandmother who lived with us at the time would stay up late to watch Johnny Carson.  I could see the television from my room, I would watch from my bed on school nights when I should have been sleeping.  I would be laughing with the pillow over my face so no one would hear that I was awake.

I've included a few other classic clips from the master...Heeeeerrrrrs Johnny.
