When my friends and relatives look at comic-styled pictures, no matter what comic I show, they all mandatorily point out that all characters and faces are looking similar to each other. Then after some time, they forget about their observation (as its unimportant to them), and I show them some other comic (sometimes from drunk duck too), and time after time, comic after comic, comic-style after comic-style they keep saying that faces are looking like one! And the best part is that I really dont understand them, I cant figure out how is it possible, that noone can tell the difference between a bald guy with fat face and small piggy eyes, and a guy with small chin and narrow cheekbones. Am I blind or something?
Sorry for my bad english.

It sounds like your friends and relatives are blind. It's kind of hard to not be able to tell the difference between a fat bald guy and a guy with a thin face.
