My favorite character. Nobody did more with their eyebrows than John Belushi.
With his buddy Dan Aykroyd
He accidentally cut Buck Henry on the head during this one:
GILDA! (and host OJ Simpson...)
From the newer stuff - Tina Fey, Amy Poehler, Kate McKinnon & Melissa McCarthy could run comedic rings around all their male co-stars, IMO. And I'm not really overly fond of female comics, either.
Will Ferrell as Mr. Tarkanian with Pierce Brosnan as the guy interviewing for the job was always one that made me lose it. So inappropriate by today’s standards.
