Last year, CBS saw almost no bounce the week after killing Partners, mostly because they brought in Two and a Half Men rather than TBBT. They got a massive bounce the next week with Big Bang, though Dancing With the Stars being just an hour was also likely a big factor on that night.
Last week, the three programs in these slots added up to 6.2. (We Are Men 1.8 + 2BG 2.3 + Mom 2.1.)
2 Broke Girls PLUS The Big Bang Theory (R) PLUS Mom Over/Under: 7.45.
