I have seen the meme of Batman slapping Robin so many times. I really want to know the origin of it. When did it occur in the comics, and why did he even slap him?
Note: Spoilers are welcome.
As recorded in knowyourmeme.com:
According to the Comics Should Be Good Archive, the panel originated from the 1965 comic book “World’s Finest #153.” The story is based around an alternate reality in which Batman believes that Superboy and Superman are responsible for the death of his father.
