A few of you have mentioned not being able to tell the blond guys apart. Totally cracks me up!
I can tell them apart, because to me, Ashton looks like a former (or current) stripper, and Tyler looks like the epitome of a bro-dude, bro-douche, whatever you call it.
Tyler looks confused most of the time, and he looks like a guy who would enjoy being called "Throttle" (didn't he proudly tell us that was his nickname?) and who gets excited by things like ... wait for it ... "Whoa! Dude! First tracks in the fresh peanut butter!" -- or whatever he said.
