If you can look it this from a comical perspective, it might help relieve some bad feelings over it. Think about it, if this were a tv show, you were the sane one among crazy people? You were the main character in a silly situation. Walking into your boss' office, and he and another dude are dressed as batman??! And he forces you to also dress as batman too? Re-dickulous lol
At the end of the show, you grab a beer with some friends, and everyone in the bar is dressed like batman, and you just shrug your shoulders at this crazy world.
This really is a funny story, and I absolutely commend you for making through. Your boss is reduck-u-lous. This isn't on you at all.
