A sardonic presence on television and the occasional feature since the early 1990s, comedian and actor Norm Macdonald enlivened the "Weekend Update" segment on "Saturday Night Live" (NBC, 1975- ) with his cutting, often scandalous comments on celebrities and politicians. Macdonald's take-no-prisoners attitude contributed to his dismissal from the variety show in the late '90s, and he bounced between failed films like "Dirty Work" (1998) and modestly successful sitcoms like "Norm" (ABC, 1998-2001), as well as numerous voiceover and promotional turns. Macdonald's acidic humor kept him in the public eye for decades until his return to a "Weekend Update" like format on "Sports Show with Norm Macdonald" (Comedy Central, 2011). It also made him a refreshingly unfettered voice in the vast and largely safe world of stand-up comedy.
