During the first trial, in the jury box the stegosaurus sits on the tyrannosaurus's right, but in one shot he's on the left.
When Robbie and Earl confront Mr. Richfield, one of the money bags jumps in and out of Robbie's right hand between shots.
When Earl and the guys are forced to work the night shift, they're seen stumbling around in the dark, implying this is almost never done. However, in a previous season episode (Honey, I Miss the Kids), Earl and Roy are seen working the night shift, complete with lights strung around the trees, as if it's a normal shift.
