The "Saturday Night Live" stars who lasted, and the ones who flamed out

From the New York Times:

Eddie Murphy, who kept "Saturday Night Live" kicking through four of its bleakest seasons, will return on December 21 to host the show for the first time in 35 years.

Murphy has kept his distance from Studio 8H ever since David Spade, then a cast member, made a joke in the 1990s about Murphy's faltering career.

In light of Murphy's long-awaited homecoming, we plotted the tenures of all 153 comedians who have been officially credited as cast members.
