Sheldon seems harried in this photo from tonight's The Big Bang Theory.

I don't always post show clips when they're available, because they're always out of context, and they're always both more and less than I want to know, and it can be a hassle, and so forth. But this one, from tonight's new The Big Bang Theory, really made me giggle. I realize this makes me kind of a cheap laugh, but when Jim Parsons is making with the physical comedy, my defenses are very low.
