Over at Ryan North's Dinosaur Comics, the perpetually-frozen-in-one-comic-strip Tyrannosaurus calculates the "Expected Real-life Batman Generation Rate." Needless to say, the odds aren't good.
North mentions that he "took the .0001 parent murder from a statistic [he] found for humans in the Americas." He also notes that the dinosaur murder rate was undoubtedly much higher than the present human murder rate, so the probability of a Dinosaur Batman existing eclipses that of a Human Batman.
Does this mean the giant robot T-Rex Batman keeps in his basement had a better chance of becoming the Caped Crusader than Bruce Wayne? Of course not, given that the robotic dinosaur murder rate has been (I'm assuming) historically quite low. [Qwantz via Newsarama]
