CBS’ Monday night line-up continued to perform solidly with How I Met Your Mother (pictured) tallying its season-high number of 9.8 million viewers, according to

preliminary overnight ratings, even though its lead-in, Big Bang Theory, actually dipped slightly to 9.7 million from last week’s 10 million. At 9 p.m., the Eye’s Two and a Half Men performed strongly (opposite Dancing With the Stars, no less) with 15.2 million viewers, a 4 percent increase from the previous week. And Worst Week, which had been struggling, saw its highest numbers since the premiere with 10.4 million viewers. CBS also dominated the 10 p.m. hour with CSI: Miami’s 15.4 million viewers.

Over at ABC, with the season finale of Dancing With the Stars fast

approaching, the reality competition’s audience grew to 19.7

million viewers last night, 1.1 million viewers more than last week. The increased viewership only added slightly to

Dancing‘s lead-out, Samantha Who?, which earned 11.1 million viewers, a minor increase from last week’s 11 million. Capping off ABC’s night at 10 p.m., Boston Legal averaged 8.5 million eyes, a dip of about 4 percent from last week.

NBC’s schedule continued to see disappointing results with its Heroes and My Own Worst Enemy but actually saw an uptick in viewers for Chuck. Last night’s episode averaged 6.8 million, 600,000 more viewers than last week. But that’s where the good news ends. Heroes dipped to 7.6 million viewers, down 300,000 from last week. Things were even worse for the canceled Enemy, which continued to drop: last night’s episode only reached 4 million, a dip of 7 percent from the previous episode.

While Fox’s two Monday series, Terminator: The Sarah Connor Chronicles and Prison Break, hardly enjoyed blockbuster numbers, they did see slight increases: Chronicles posted 5.3 million, a 100,000 boost from last week, while Break hit 5.9 million, up half a million viewers.

The CW’s Gossip Girl and One Tree Hill both struggled to reach 3 million viewers last night. GG (2.9 million) and OTH (2.7 million) dropped 6 percent and 10 percent, respectively, from the previous week.
