I'll give big Zack this: he's FAR more articulate than Sean "you know, you know, you know, you know, you know, you know" Allen. If Zack's dumb, Allen is too stupid to breathe without a respirator.
Plus, I gotta give "props" where they're due: Zack is a freak in the gym. And yeah ... 300 lbs. or not, the fucker did a couple sets of failure on the Smith incline, hit the pec deck and only THEN went to bench with 495, the first rep of which he paused for like three seconds on his chest. When the fucker's fresh, he's done 585 with good form.
Smart? No. But impressive.
