You're absolutely right, SNL hasn't been funny since the days of John Belushi (well, "Mister Robinson's Neighborhood" was good;)
Haven't watched since then, though!
The only time I watch SNL now is when Christopher Walken hosts. He is fantastic.
I saw a skit or two last week because my roommate wanted to watch. They were nothing short of pathetic. Liam Neeson looked completely out of his element and the audience gave polite laughter only. It sucked.
