Seasons: Prank Day

It's come up a couple of times in my game. Sims were pulling pranks on each other all day. The first time it happened in my game it was also the same day as the Humor and Hijinks festival. My sim was working on her mischief skill anyways, so it was perfect. The other time I was playing a child brother and sister pair. It wasn't Max, from Windenburg, but the kid was very much like him. He even got a vampire to join in on the fun.

I don't know if you have had the National Brawl day come up, but if you haven't, don't worry, those fights don't mess up any relationships either.
