Anyway, today at my rugrat's Saturday Japanese school, it was parents' observation and participation day and Mamemaki. Some of the fathers (including yours truly) dress up as Oni (demon ogres) while the kids throw nuts at us while shouting "Oni wa soto, fuku wa uchi (Oni go out, Luck come in)!." Normally you're supposed to use soy beans, but with so many small kids, they decided peanuts were cheaper and less likely to cause a choak hazzard for the toddlers and small kids.
After a while it became a free-for-all with the assembly room floor covered in crushed peanut shells.
So, what crazy or interesting thing did you have to do as part of your spouse's traditional cultural celebrations? Join any carnival parades? Nail yourself to a cross? Do tell and post pics!
