Superman didn't always fly. 

The original comic book Superman could leap tall buildings in a single bound. But then he had to come right back down to Earth—because he didn't fly. It wasn't until the 1940s, when animators for a new animated series decided it would be too difficult to routinely draw him bending his knees, that it was decided that Superman could take off into the air. Readers got to see smooth animation, and a superhero gained a new power.

Not sure if 100% fact, but the reason why we can't travel back in time or ever met a person that can travel back is because that person could wipe out whole humanity with his germs, no matter if like bad ones or good one in your guts (like this flora they call) it could wipe out everyone as there is no collective immunity.

A dozen bodies were once found in the basement of Benjamin Franklin's house in London. 

The bones were discovered during a 1998 renovation of the house and were identified as being from nearly a dozen people, including six children. The most plausible explanation is not mass murder, but an anatomy school run by Franklin's young friend and protege, William Hewson. That's not to say there wasn't any funny business going on. "The resurrection men could deliver bodies stolen from graveyards to the Thames wharf at the bottom of the street, while there was a weekly public execution at the gallows on the other side of the garden wall."

Shaq only ever made one three-pointer.

Tigers, Lions, Hyenas, Elephants, Rhinos and Hippos were all once native to the UK up until about 20,000 years ago.
