Faster than an overhand smash.  Able to berate a chair umpire in a single bound.  Look, up in the sky…it’s a bird…it’s a plane…it’s Serena Williams in a set of Superman pajamas.  The tennis star uploaded this picture to her Twitter account, and while it may not be the sexiest choice in sleepwear, it’s quite appropriate if she ever wakes up in the middle of the night and has the sudden urge to fight crime.

Now let’s see her get away with wearing this at superhero onesie at Wimbledon without stirring up some major controversy. Now that would be super, man.
