We used to do this for every earnings call.

We printed up bingo cards filled with buzzwords, products, trends, things we thought the analysis might say, etc. We charged $15 per card, all of which was pooled and given to the charity of the winner's choice. When the CEO caught on, he started matching the donations.

There was a reverse version of this played too. We voted in Slack for some weird word or phrase that the CEO or CFO had to say during the earnings calls. They were super awkward and totally unrelated, and the goal was they had to weasel the phrase in somehow. It was pretty funny.

(For someone else in the know, without giving away the company, do you remember any of the wacky phrases?)
