Monday's ratings recap:
Dancing with the Stars averaged 20.16 million total viewers over its two-hour run, dipping just 4 percent week-to-week. Trailing a House repeat, How I Met Your Mother (7.4 mil) didn't deliver a very big bang in Sheldon and Leonard's time slot, dropping 20 percent from its last regularly-scheduled episode.
Weakened by a Two and a Half Men repeat, Rules of Engagement plunged 17 percent, to 9.43 mil. 24 hit its first skid in a while, slipping 9 percent, while Heroes (6.48 mil) sank to a new series low. One Tree Hill held steady at 2.26 mil.
