Him not recognizing characters with distinct features doesn't really make sense, I know it's a gag but it's not really funny after how many times it has been used. I think it would be much more logical and interesting for him to mistake others as characters he already knows who share the same distinct features. For example, him mistaking someone with red hair for Keith. I think this has the potential to be more than just a gag and could contribute to story progression, meanwhile the "Who are you?" gag could still be used for those without recognizable features.
