While learning from one's failures is theoretically a wise thing to do, the concept doesn't apply to Wally at all. Wally is successful at shirking his duties, consuming mass !$%*!$%*!$ of coffee, and pointing out the epic failures of those around him. He knows everything he needs to know.
PHB looking in one direction while Alice lambastes heightens the "kick in the a$$" effect. Then he's frozen like a deer about to be hit by a truck, so has to look back at her from the corner of his eye, more enhanced effect. Then Wally runs him over.
