One episode that stands out among the others is Season 6, Episode 12, "Scott's Tots," which received the most mentions. Reddit user u/jdeluca87 wrote, "SCOTTS TOTS FOR SURE! Took me 3 attempts to finish that episode," and u/Alternative_Body 7345 commented the episode "makes me want to hide under the couch."

Throughout the series, Michael inadvertently exhibits homophobic, racist, sexist, and generally offensive behavior, but the only ones who suffer are his employees, and it's difficult not to feel sympathy towards a man who so desperately just wants to be liked. However, in "Scott's Tots," Michael's bad judgment and overall stupidity have far-reaching consequences. The episode reveals that 10 years earlier, Michael promised a class of underprivileged children that if they graduated from high school, he would subsidize their college educations. When it comes time to pay the tab, Michael has to skip out on the bill. Michael admits that this one was by far the most generous out of all the empty promises he's made.

We have to agree with u/interestingmongoose's critique, who stated the episode "always makes me cringe."
