I've been continuing to enjoy the new CBS sitcom "How I Met Your Mother". It had the best pilot I've seen since "Dharma & Greg"'s, and most of the episodes since then have maintained that level of quality, including last night's New Year's Eve episode. Barney's blog is pretty funny too. (Especially the Halloween logic puzzle!)
Also really entertaining is "The Andy Milonakis Show" on MTV2. It's a similar kind of bizarre/surreal/infantile humor as "Sifl & Olly" and "Stella", except without all the parts that actually make sense. Worth checking out just for the theme song.
And if you didn't already hear the sad news, "The West Wing"'s John Spencer (Leo McGarry) died of a heart attack on Friday. Still not clear how "The West Wing" will handle it, with 8 episodes left to be produced for this season.
Edit: One more thing I almost forgot: "Lazy Sunday", a hilarious music video from last weekend's "Saturday Night Live". (Warning: that's a link to the video itself, with sound.)
