Sometimes, Batman gets a few quiet days when there's little crime in Gotham City, and he can spend his costumed nights enjoying the little things in life. That's when we see a different side of Batman, one that rescues kittens and enjoys bubble baths.
Sarah Johnson creates these nifty "Ordinary Batman Adventures" animations. I wonder, does Batman bathe in full costume, or just the cowl?
Edit: Sorry the gifs are so twitchy. I'd recommend heading over to Sarah Johnson's tumblr to see them all their less frenetic glory.
