Did anyone ever tell you, you look like.............

So I was watching that incredibly stupid movie Land of the Lost this weekend when I made the discovery that one of my students is the spitting image of the character Khakka..........well he's not covered in fur from head to toe but damn I am telling you they could be twins. It's really kinda freaky how much they look alike. So my question is do you think it'll damage his psychie for life if I tell him he's the spitting image of a fur covered cave man? Ahh what the hell, he's goes out of his way to be a pain in my ass daily, screw his fragile psychie.
