Jokes aside, what are the upcoming events? 
- Christmas
- New Year's Eve
- Valentine's Day
- Patty's Day
- Easter/April Fools

Most of those are regulars and don't need much dress-up. There might be room after new year's for an irregular themed event. 

If you want it, even a trash idea like that, claim it and put the work in doing the necessary shilling and organization.
