Monday night's major movement:

" With an audience of 9.77 million (up 500,000 week-to-week), How I Met Your Mother had its best outing since the season premiere. Lead-out The Class, however, slipped 580,000, to 8.12 mil.
" Heroes surged 1.2 million to 14.27 mil, virtually matching its series high (set by the Sept. 25 premiere). Now go out and save the damn cheerleader!
" An audience of 6.21 mil turned out for Justice's first fresh Monday episode, a shade less than what Vanished was drawing in its former time slot, and about 800,000 heads fewer than what Spy Daddy was getting on Wednesdays.
" What About Brian, which gave Studio 60 a scare last week, dropped 2.3 million (to a hair over six mil), while Studio 60 stayed put with 7.69 mil.
