He loves Superman and Batman

I didn't realize Robin Williams was such a nerd until I saw him come into a comic book store on 18th & Geary. He almost had a full beard, was wearing an orange rain coat, and darted immediately for the superhero comics (he loves Superman and Batman). I didn't even know it was him until the store owner greeted him by saying "good afternoon Mr. Williams". Apparently he is a regular but he goes incognito like that every time he gets an urge to nerd out.
