Batman having a recording of a heartbeat softly play in his suit so that Superman thinks he has two hearts to throw him off his scent because he's paranoid, but then one day it breaks and Superman freaks out, because "Batman where did your other heartbeat go?!!?!" and Bruce panics and says: "I split into two," like he's some sort of cryptid and everyone goes ???, luckily he has Robin to introduce them to. It's not until much later when they all reveal their identities that they learn that it's not true and all the bats and birds that are running around were not parts that ripped free from Batman. Though not before the whole family has had a whole lot of fun creating nonsense rumors just to fuck with people.
