The quote is this:
"It's wiser to be alone but happy, than with somebody who does nothing while you're doing everything."
It's popped up (in various forms) on my Facebook news feed, like, three times now. It's always on a poster, and it's always attributed to Batman.
Google has been no help (it just leads to more mentions on Twitter, etc).
Does anyone know the SOURCE of the quote?
Because I really think I'd like to read/watch it.
Thank you :).
