Dealing with the ongoing comment apocalypse in the "Chuck" episode post has occupied far too much of my day, so I'll be quick on last night's "Big Bang Theory." Sheldon's Tuvan throat singing was funny (even if they went to the well once too often), and I liked his various schemes and rationales for getting to go on the trip (particularly the pancakes in the shape of Leonard's favorite fictional characters), even if I don't believe that Penny would have made the offer she did in the laundry room. (Fienberg, on the other hand, argues that Penny was completely insincere and just trying to get him to go away.) Also, Raj's list of depressing Valentine's Day rituals was very funny. What did everybody else think?
