Synopsis: We start with Mike, Lawrence and Gordon looking at a bright green Halloween mask that's really ugly. As Martha could tell you after one Valentine's day, Mike is stalled at the wanna look at my chewed-up food phase of development and buys the thing, takes it home and causes John to marvel that he spent fifty bucks on the ugly, creeps-inducing thing. After delivering a speech about celebrating beauty when there's so much ugliness in the world, the part of John that wants to be a gross-ass kid makes him wanna try the thing on.
Summary: We're seeing yet another battle between the (easily frightened stick-in-the-mud) 'adult' Lynn and the (obnoxious and naughty little jerk) 'child' Lynn. The tsunami of 'jokes' about bodily functions tells us who won....and it wasn't us.
