We were having a meeting and our boss was bringing up on-call schedules, and how the new policy was going to be much stricter, as well as a three missed calls and you're fired deal.

In the middle of his talk, my coworker loudly announces 'excuse me' as he reaches down to his bag, pulls out a glock, lowers the slide to make sure its loaded, then places it back in his bag. Then with a lot of enthusiasm, waves his hand saying 'Please, continue.'

Our boss said something like "I'm sensing some push back on this so we're going to rethink it before we go further." The changes never materialized.

In fairness we had all a bit to drink so this was pretty hilarious at the time, but in retrospect it was a pretty fucked up joke.
