Steven Seagal
It’s unclear what made Steven Seagal “hard to work” during his 1991 hosting stint, but he’s never been allowed back on Saturday Night Live. Moreover, during an on-air monologue with Nicholas Cage in 1992, Lorne Michaels referred to Seagal as the biggest jerk to ever host the show.
The Replacements
The Replacements, a legendary Minneapolis punk band, were set to break into the mainstream when they were booked for a 1986 appearance on Saturday Night Live, but they blew it. Rolling Stone reports that the ‘Mats (as fans call them) “got drunk, said the f-word just off mic during their first song, switched clothes for their second, and rang up $1100 in hotel damages.” Lorne Michaels was so furious with the band that he wanted to ban all artists from Warner Brothers Records as a form of retaliation. The ban was eventually limited to The Replacements.
