Anyway, a quick look at the ubiquitous photo of the two mules standing face to face reveals a lot about how their very different upbringings may have shaped them. Star (the car chaser, on the left) has an almost sleepy, bucolic look on his face and is wearing a very gentle snaffle bit bridle—a sign that he's a pretty easygoing guy and, at any rate, not very hard to stop. Not a supergood sign in a racing animal. Gem, on the other hand, looks like he's been fed crack. He's wearing blinders to help him keep his eyes on the prize, and he's got his tongue jammed over the top of a strong racing bit. All indications that he's a little more jacked-up, personality-wise, and also probably more excited about the idea of actually winning.
