In the recent months, we've seen late night show hosts announce retirement, retire and  start their careers. There will ever only be one King of Late night - Johnny Carson.

Johnny took over the "Tonight Show" in 1962 and walked through the stage curtain over 5000 times until May 22nd 1992.  I remember watching him when I was a kid. He had a style of his own and influenced decades of comedians.

Johnny Carson defined Late Night.
