It's difficult to believe that there have been 39 seasons of "Saturday Night Live." The first show aired on October 11, 1975, under the original title "NBC's Saturday Night" and has run consecutively ever since. Many famous faces have graduated from this stellar cast of performers, comics and writers and so have many of their characters.

Putting together a list that spans so many talents and decades is like picking your favorite child, so let's just say that these are the 20 greatest characters "so far", 'cause as is with the case of "SNL" characters are always evolving and changing. Who knows what greatness this "Saturday Night" may bring?

1. Roseanne Roseannadanna

Gilda Radner was one of the most expressive female comedienne's ever on television. She could make you chuckle first with her facial expressions, and only then did you fall down laughing with her delivery of a one-liner. She was "Weekend Update's" consumer affairs reporter who gave curt and opinionated editorial replies to current issues. Roseanne was crash and deadpan, based on a former anchorwoman on Eyewitness News in New York. Rose Ann Scamardella.

2. Wayne Campbell and Linda Richman

From the opening bars of the intro tune to the cable access show "Wayne's World," viewers of "SNL" knew they were in for something unique.  Wayne Campbell (Mike Meyers) was a metal head with a heart and he hosted the show with his timid friend Garth (Dana Carvey). Meyers and Carvey were so over-the-top in their characterizations of these two lovable meatheads that viewers couldn't wait for their segments to air.

On the flip side, Meyers was superb in his characterization of his mother-in-law, also Linda Richman. The character of Richman hosted a television show called, "Coffee Talk", where she extolled the virtues of Barbra Streisand. It was one of the funniest bits ever made for the show and stars clamored to be included in the fun.
