Will Ferrell, move over. Will Sasso is the funniest sketch comedian named Will on television.

The beefy Canuck is spotlighted each week on Mad TV, the often overlooked late-night comedy gem.

While Saturday Night Live gets all the press, Mad TV keeps cranking out edgy, sharply-written and brilliantly acted sketches that are laugh out loud funny.

Tomorrow night's effort (11 p.m. on CH and Fox) is no exception. There's an appearance by Malcolm In The Middle's Frankie Muniz, who is hyping his new flick Big Fat Liar with co-star Amanda Bynes. A barely recognizable Sasso deflates pompous Inside The Actor's Studio windbag James Lipton, all disheveled and stripped down to his undies as he stumbles through a half-assed interview with the two teens.

I saw this sketch a few weeks ago in Hollywood on a visit to the Mad TV set. They tape every Friday night at Hollywood Center Studios, Building 2, right next to the set for Martin Short's corpulent critic spoof, Jiminy Glick.

I'm sitting with about 200 rabid Mad TV fans, many who line up every Friday. It's a five-hour party, with more singing, dancing and clowning going on in the bleachers than on most sound stages.

The taping takes about five hours and is spread over several sets that extend like stalls along a cavernous studio. Amanda Bearce, who used to star in Married...with Children, directs. Sasso is in several sketches, and he's a hoot.

Especially in a three-parter with castmate Frank Caliendo. The two play film capos Robert De Niro and Al Pacino ordering ice cream at a Baskin Robbins. Caliendo's Pacino is all wide-eyes and over the top as he stammers and stalls; Sasso's trigger-happy De Niro has that goofy grin with the rolled tongue stuck in the middle as he cheerfully whacks the ice cream vendor.

Sasso has a gift of nailing great actors. His heavily edited James Gandolfini is F-in' hilarious, especially in last season's show-stopper, The Sopranos on Pax-TV. (The clever premise: The profanity-laced series was edited down to a jerky three minutes for the family-friendly broadcaster.)

The same night I was there, Man Show bad boys Jimmy Kimmel and Adam Carolla were playing Olympic commentators with Mad TVer Michael MacDonald, who was made up as U.S. figure skater Scott Hamilton. This sketch will probably run next week when the Olympics begin. You'll see MacDonald goof on NBC (he waves around a liquor bottle in a nod to NBC's tipsy new advertising policy). You won't hear a lot of the X-rated ad libs that the threesome played to the studio audience. ("I'm getting a Zam-boner," said Kimmel.)

Catch Sasso while you can. He's leaving at the end of this season and is mulling his own sitcom deal. Several other Mad alumni, including Orlando Jones, Artie Lange and Nicole Sullivan, have found fame elsewhere. The only original, Debra Wilson, is still tying herself up in astonishing pretzels as she slips into characters as diverse as Lorraine Bracco (again, that brilliant Sopranos sketch), a skeletal Whitney Houston and a hair-flipping and bottom heavy Oprah Winfrey. Alex Borstein (Bunny Swan), Mo Collins and Andrew Daly all make me laugh.

Skip SNL this weekend and give MAD TV a shot.
