A woman at work today was all excited to show me a Rolling Stone cover, because I look "just like" Louis CK. Well, sorta.
It's not just false modesty to note that he does look better, whatever similarity we have. What is more pertinent is why people usually say that based mostly on fairly accidental traits, such as hair style, glasses, facial hair, and the like. He is balding, and our hair, such as it is, is similarly cut. We have similar goatees. Our general features are compressed, eyes a bit closer together than average, though mine are tighter (worse) than his on that. Mouth not visible (goatee), eyebrows different. Noses unremarkable.
My face is animated when I speak, so I may give off something of the same vibe. But I'm not seeing it. I like him, though. There are worse people to look like.
