I was wondering and thought it could be fun to get suggestions of what might be the most relevantly subversive thing to put on the card.  I guess the second question is what are the odds it would actually get through whatever scrubbing application a bank uses.  
Just a few examples.

Please put suggestions in the comments if you feel subversive to banking.
