dude hasn't been funny for decades. it's amazing that you could snort your ability to entertain away in the 80's and still depend on your past roles like diminishing returns don't exist. there is still hope for you, chevy chase.

also, what is with robin williams playing the same creepy guy role every few years (wasn't he just on tv playing his former role from 'insomnia' / 'one hour photo' / etc.)? i guess when you act the fool every time a camera is on you, showing some amount of self restraint / dignity makes you seem like a serial killer. serious acting range - from someone with adhd to someone who takes medicine for adhd.
