Quitting my job at Amazon, only second to going on the record and explaining to my boss that the reason I quit was "oranges" - I did this because I knew my boss would be reprimanded and asked by HR / mgmt "why did your employee quit because of this reason here?" and have to explain why I quit because of "oranges". I should add, that almost all of the other lead engineers moved to other teams or also left.

It's taken me more than a year to un-learn and cleanse my head of all the stupid games I had to play at that bullshit company.

Finally, quitting drinking. I never really drank that much, but at this point I don't really crave alcohol at all.
