Carter Has An Imaginary Friend...

...or at least an invisible friend.

How do I know?

When he runs he runs like someone is pushing him at the waist from behind...hands up & waving a la "Kermit the Frog", torso tilted and head thrown back.

Its almost as if he's saying (screaming), "Look out! This train's outta control!"

P.S. I love it :D
