What I liked: Shawn and Cory sleeping in Turner's class, Shawn challenging Turner on everything he says (What if I choose not to do the assignment?), Lonnie lying to Eric about her having to strip both of them naked when he was unconscious in the car, and his reaction (Oh great, I'm awake for the soup), amongst other moments.
What this episode did well, like so many other episodes from this show, was combine humor with emotion. All the parts above were humorous, and the ending, with Shawn and Cory talking, was pretty emotional. That's why this show is so great, to me, is because they combine humor with emotion and it makes the episodes really entertaining. This isn't one of my favorite episodes of the series, or even the season from which it came, but it still is a pretty amazing episode. B+/A- is my final grade
