On October 8th, 1985, the iconic actor, comedian, and "Saturday Night Live" cast member, Chevy Chase, was involved in a notorious backstage brawl with SNL writer, Michael O'Donoghue.

The incident occurred during the show's 11th season premiere, hosted by Madonna. Tensions were high between Chase and O'Donoghue, who had a history of creative differences and personal animosity. According to witnesses, the altercation began when Chase, who had returned to host the episode, made a derogatory comment about O'Donoghue's writing. The writer retaliated by hurling a punch at Chase, and the two ended up grappling on the floor.

Cast members and crew quickly intervened to break up the fight, but not before Chase sustained a broken nose and O'Donoghue a bruised ego. The incident sent shockwaves through the entertainment industry and solidified the volatile reputation of the SNL work environment.

Despite the altercation, the episode aired as planned, with Chase sporting a visible band-aid on his nose throughout the broadcast. The fight became a notorious moment in the show's history and a testament to the intense creative passions that fueled its success.

In the years that followed, both Chase and O'Donoghue went on to have successful careers in Hollywood, but the memory of their backstage brawl lingered. The incident remains a fascinating footnote in the annals of celebrity history and a reminder of the high-stakes, high-pressure world of television comedy.
