Steven Seagal
In 1991, when martial artist and actor Steven Seagal hosted Saturday Night Live, everyone expected a boundary-pushing performance from a comedian and rocker. However, the outcome was quite the opposite. Seagal's eccentric behavior and unhinged performance made the cast extremely uncomfortable, including the beloved Chris Farley.
The cast and crew became frustrated and vexed by Seagal's conduct to the point that they considered doing the show without a host. Despite their struggles, they proceeded with the episode, resulting in one of SNL's most bizarre and awkward moments. Due to the uncomfortable experience and poor reception, Steven Seagal was never invited back to host the show again.
