A 31st Century Halloween

Here's a repost from 2006 as I was too lazy to come up with something new.

How do they celebrate Halloween in the DC Universe?

They put on masks and stage pranks


They put on fat suit costumes and gorilla costumes (in the DCU? Of course!)


They dress up as infants


They put on outdated clothes


They even try on fetish wear


They go to costume parties where lots of others are also dressed as heroes


They dress up as pirates, yarrrr!


They dress up as zombies. Mmmmm, brains!


They dress in drag


They dress in group costumes
