Look, we don't endorse acting in really awful sitcoms whilst stoned out of one's gourd. But we could be persuaded to endorse such an action, if it means more moments like this one. There's lots of moments in which Barry Williams demonstrates that he is very high in this scene. Tripping over the bike pump, his lazy high-guy wave, his fucking eyes, which are super squinty.
However, my personal favorite is when he reacts to Cindy's voice by turning completely wrong way, and then corrects himself. ("Oh Shit, the script said turn right!" Only high people trust their memory of a script to react to a voice, as opposed to actually just reacting to the voice.) Barry has admitted he was high for this scene. Good on him.
