Every single one that popped to mind has been covered. Here's on that might not be a "best ever" category, but defintiely good for a couple of laughs.

Col. Angus was pretty awesome...

I'd have to youtube a while.

Right now.......
Eddie Murphy, Reggae band.

Kill dee white people..but buy my record first.))))))

Sorry, but nothing from the current/recent SNL cast should even be considered lol.

The first Celebrity Jeopardy had me rolling w/ Norm as Burt Reynolds

Jim Carrey w/ the Roxbury club guys was on point and hilarious.

Chippendales w/ Swayze and Farley

Most anything that featured Phil Hartman (RIP). My favorite was him as Clinton in McDonalds. You learned two things, he eats like a pig and there are many things we don't tell Mrs. Clinton.

I've never been a big Jim Carrey fan, but my dad never watched SNL and I remember recording this on my VCR in '96 and showing it to him. He discovered a whole new world of comedy. Jim Carrey the lifeguard, and if you notice, Will Ferrell hasn't changed a bit.

That entire SNL ep with Carrey on it was hilarious.

Van down by the river
Cowbell
Ambiguously Gay Duo
Suck it Trebek

This the one where he’s Neil Diamond, and the Rock is Bigfoot and they’re doing a record together is so ****ing funny!!

Has anyone mentioned the horrible boss Will Ferrell vs Pierce Brosnan? That one is very underrated.

"I HAVE BEEN DOING COCAINE AND LIFTING WEIGHTS ALL DAY!! I AM READY FOR YOU"

"OHHH SCOTT JORGENSON. I LOVE IT I LOVE IT I AM ACTUALLY GOING TO MURDER YOU"

The Bronx Beat sketches (Mya Rudolph, Amy Pohler) were incredible.
