Viewers: 10.49 million. Not only is this the most-watched episode of the season, if you don’t count Ten Sessions (which largely owed its ratings to its guest star), it’s the most-watched episode in almost two years.
Adults 18-34: 3.9/10 – this is a series high.
Adults 25-54: 4.7/11
Households: 6.4/10
Compared to other networks: Behind ABC in viewers again (this time with A Charlie Brown Christmas), but first in its time period in households, 18-49 and 18-34. [In fact, HIMYM had the second-best 18-34 numbers of everything on Monday night, coming in just behind Heroes.]
Compared to other CBS comedies: Last in households, third in viewers (ahead of Worst Week), and second in 18-34, 18-49, and 25-54 (behind Two and a Half Men).
CBS spins it:
This is MOTHER’s best adults 18-34 performance ever, best delivery in households since February 5, 2007 and best viewer total since March 24, 2008 (the first Britney Spears appearance).
