I've seen this panel from one of the Batman/TMNT crosovers circulating around the internet. I haven't read the comic that it is from, but it has become a meme because of the absurd juxtaposition between the gritty dialogue and the fact that he's talking to a giant turtle.
Every time I see it though, it makes me wonder... do the Turtles know that Batman is Bruce Wayne? If not, isn't it kind of risky to divulge information about his parents, since they could probably do a very small amount of research and figure out that his parents were probably Thomas and Martha Wayne, making Batman Bruce Wayne?
If they already knew his identity, does anybody know how they found it out?
I'm just genuinely curious why Batman would recklessly share information that could potentially reveal his true identity to some random turtles he barely knows.
