When I listened to Chevy Chase on the commentary tracks, he kinda sounds like the out of touch old guy in real life too. He seems to have absolutely no idea what a commentary track is or why they're doing it.
See, that's dangerous. When the old guy isn't aware of what is and isn't funny, you end up getting Chase playing Pierce as a racist asshat instead of a clueless old guy. He thinks Pierce is supposed to be an asshat. After a while, the writers just started writing him that way.
See Betty White for examples of old people who get it.
