Chuck's episode on December 30th was called "Chuck Vs. The Baby". It's an episode that has seemingly split Chuck fandom between people who absolutely adored for its "touchy-feely" content about babies and moms and defacing the dream home you don't own yet and people who had major problems with its nonsensical plot and lack of continuity with Chuck mythology.

It's also an episode that had a drop in Adults 18-49 rating to a season low, driven mostly by a rather large 23% drop in the Male 18-49 demographic. Women 18-49 dropped only 8%.
Is there a connection between the subject matter and the ratings results? Discuss.
(Edited to add for full disclosure: There was a minor College Bowl game on ESPN that got a 1.1 A18-49 rating. This was an improvement over ESPN's ratings the previous week.)
Since I didn't post a Time-shifting report today, I'll add as a bonus the top 10 Timeshifted shows for the week of December 12th, 2011. Chuck doesn't usually make the Top 10, but it did this week in a week of many repeats.
Grimm and the Terra Nova had large lifts, but the now-canceled Prime Suspect was the winner.

Note that we compute our percentages off the 2-decimal point rating. TV By the Numbers rounds to one decimal point and gets less precise numbers.
