Growing up in the 1960s, I was introduced to “Bizarro World” by DC Comics. Bizarro World was featured in comic books (now graciously re-named “graphic novels”) as a planet where everything and everybody is inverted.
For example, on Bizarro World (otherwise known as Htrae – “Earth” spelled backward), bonds are marketed as “guaranteed to lose money.” Bizarro Aquaman can’t swim. Halloween trick-or-treaters give fruit to the houses they visit. And so on.
