There was a period where I worked for certain owl-themed social media software company and, as part of building internal community goodness, there were occasional festive parties/activities put on by various departments who were allotted at $300 budget and attempted to constantly one up each other with what they could pull off.
My beloved department (community) was paired with another and chose the theme of 1980s homecoming dance.
I played the role of principal, making various announcements and instigating various contests and hi-jinks including a poorly executed “king and queen” election which was thwarted by an incompetent accountant.

Maybe one day some things will surface again, probably not.
