DOCTOR MIZZIERI'S COMEDY BITE OF THE DAY 
"Comedy is the greatest form of intellectual stimulation, provided you hit your targets and avoid the air-borne fruit." 
Doctor Bruni Mizzieri

Dean Martin and Foster Brooks  - The Dentist - On or About the Early 70s
You wouldn't want this guy poking around your mouth, regardless of what your insurance covers.

Robin Williams - Tonight Show Debut - 1981
Here is Williams ranting in his unique chaos by design, the comedic equivalent of a tiny boat on choppy waters, the ride becoming increasingly exhilarating, and yet the boat never quite flips over.  

I'm Against It - Groucho Marx in Horse Feathers - 1932
From Broadway to Hollywood to Television, Groucho Marx did as much for comedy as Einstein did for physics.  

Wizard of Oz - Alternative Ending - MadTV - May 2004
I always preferred the wicked witch over Glinda who could have sent Dorothy home  right from Munchkinland and  then taken the Yellow Brick Road to the Oz beauty parlor to get rid of that horrible hairstyle.  

Last Voyage of Star Trek - SNL - May 1976
I begin this comedy journey with the last voyage of the Starship Enterprise.  Belushi is an unlikely Captain Kirk, but pulls it off brilliantly.  Watch Spock cry as they confiscate his ears.
