The zombie episode definitely made me go 'oh, I see why people think Stan is hot now'! But I did once see him described as having 'a face like a pair of greying underpants with a bollock sticking out of them', and I'm never going to be able to forget that; it's horrifyingly accurate.

I encourage you to go back to that fic! I'm vaguely playing with the idea of writing something where Stan never gets his memories back.
