The debut of the ABC sitcom about three guys (Christopher Moynihan, Mather Zickel and Dan Folger) sussing out what it takes to be a modern man (and whether it includes using pomegranate body wash) grabbed 7.8 million viewers at 8:30/7:30c, posting a 2.4 rating among industry-prized 18-to-49-year-olds — third in its time slot by both measures. Reviews deemed the show insultingly bad.

At 8/7c, a week after Tim Allen's new sitcom debuted to 12.95 million viewers, the show had 10.20 million tuning back in — a 21 percent drop. It also garnered a 3.0 demo rating, down from 3.5 a week ago.

Of course, ABC's sitcom tandem had to go up against CBS' NCIS, which attracted 19.01 million viewers (3.8 demo rating), as well as the first half of a Tuesday night edition of The X Factor, which averaged 10.15 million (3.8) over two hours. Also in the first hour of prime time, The Biggest Loser on NBC drew 5.04 million people and The CW's 90210 1.44 million.

At 9/8c, NCIS: Los Angeles attracted 15.39 million vs. Dancing with the Stars' results (13.55 million), the second hour of Loser (5.25 million) and Ringer (1.79 million) — which The CW is trying to give a boost by airing numerous reruns and recently gave a full-season order.

Prime time's final hour Tuesday again was won by Unforgettable, which drew 11.34 million viewers vs. Body of Proof (9.50 million) and Parenthood (4.98 million).
