Martin Laurello's Had Eyes on the Back of His Head
Martin Laurello first became known in the 1920s as "Bobby the Boy With the Revolving Head," before graduating to "Revolving Head Man" and finally the "Human Owl." To be fair, those aliases did get progressively better, but to be slightly unfair, they're all still pretty terrible. Though we guess Human Owl is okay -- sort of a store-brand Batman.
As you may have guessed by now, Martin's power was the ability to turn his head all the way around.
"How many times have I told you to stop doing that when you're talking to me!"
That's not a trick photo -- they didn't have Photoshop in the '20s. They had scissors, glue, and markers. They couldn't pull that off. But just in case you still don't believe it, here's some footage of Laurello for you.
In fact, according to Laurello, anyone could do what he did -- all it took was pushing his head farther and farther every day for three years, until he could ogle his own butt. Although the fact that he had a dislocated spine to begin with probably helped a bit. But Laurello possessed more than one talent. He had to. He made his living as a performer, and his whole head-rotation schtick lasted, what, about 4 seconds?
So he began making accusations about audience members' mothers and their activities in Hell.
