Last night's episode continued the trend of building on lead-in Two and a Half Men in the adults 18-49 demographic. Both shows' ratings were down from the previous episode due to stronger competition from ABC's The Bachelor.
The Big Bang Theory was watched by 15.61 million people, coming second in total viewers. The show tied for first in adults 18-49 with a 5.9/14 rating, up from Men's 5.7/14.
