"He can't move his legs and body away! That's cheating!"
Picking on Prince Fielder for being fat is like picking on Jupiter for being fat; neither one can feel it. The best thing about this clip is how long it takes for the idea of taking a step to even occur to Prince. That being said, there's no doubt that he is an intimidating physical beast - the runner here appears to be trying to flee his maw, before being drawn back into his inescapable gravity well. Put him out in center field and you could just let all the balls and runners fall into his pull.
