Batman and the dollar
People can find all sorts of weird things in the US currency. You’ve probably seen people folding a $20 bill in such a way to recreate the burning Twin Towers. And lest we forget those infamous TMNT dollar bills that are probably invalid. Those are pretty neat.

What’s also pretty neat is that you can find Batman hidden in the $1 bill. If you look closely at the text, you’ll see his mask in the E in ONE. And if you use your imagination, it looks like the D in DOLLAR looks sort of like the Batmobile. You can probably find Robin there somewhere if you look hard enough.
