About this time last year, "Chuck" was on the bubble. Would it be back for a third season? No one--including the producers (and, most definitely including the network, who should have known)--knew. Then the fans kicked in and bought a whole lot of Subway sandwiches and it dawned on someone at NBC that they didn't have any good shows on. So they decided to replace a whole hour's worth of viewing with a tired comedian and announced that "Chuck" would be coming back ... after the Oleolympics, and only for fourteen episodes.
