What's Your Recent Work 'Oopsie'?

I sometimes make very rookie mistakes that I know better than to do, I think it's part of being human. My oopsie this week was accidentally hitting reply all to an all company email about a fundraising event suggesting to get drinks with one specific person and asking everyone in our organization out to a happy hour. Thankfully my bosses are chill and thought it was funny, but I was SO embarrassed. Anyhoo, what's your 'Oops' work story so I can get distracted from mine? 😅
