Rob Roy,
I gotta agree with your list. I have to admit, I never thought of Buster Keaton as funny - simply amazing at times, but never really funny.
But my additions to this thread (and not my complete list, by any means):
Funny:
MST3K
The State (no longer in production)
Kids in the Hall
Space Ghost Coast to Coast
Not funny:
Ellen
Anything following NBC's
Friends
The other Wayans brothers
Jerry Springer (and I paid money to see his movie)
