The way things worked out last night, I watched the first forty minutes of Chuck by myself, and then we went out to dinner, after which we watched Heroes, and then, since there was just enough time before The Daily Show, we watched the end of Chuck.
Note that jonbaker does not watch Chuck and did not want to be filled in as to the plot. He pretty much ignored what was going on on screen in favor of the book he was reading.
He did look up in time for the party scene, and to see Chuck and Morgan's costume. "Oh, cool. They're a sandworm."
See why I love him? :)
