Two years ago, Hemi broke his hip and needed surgery to fix him. The dr said after a year we'd never even know which hip needed surgery. It didn't even take that long. The only thing that reminds us is when Hemi sits like this.
His leg bone is not attached to his hip anymore and while his tendons and muscles keep it all in place, he still has some flexibility with it and he likes to show it off.
Or he's just being lazy.
Hey, who you calling lazzzzzzzzzzzzzz......
