On TV tonight
I Want a Dog for Christmas, Charlie Brown!, 8 p.m., ABC This isn't the classic Charlie Brown tale, but rather that 2003 effort that resurrected little-known ReRun, Linus and Lucy's little brother. You remember him: He spent most of his time in the strip on a baby seat strapped to his mom's bicycle.
Third Reich, 9 p.m., History This is a two-parter that hopefully will horrify enough ignorant people that they'll quit comparing modern-day leaders to Hitler. Then again, they probably won't.
SEASON FINALE The Biggest Loser, 9 p.m., NBC Who cares who wins? Jillian Michaels is leaving!
Gordon Ramsay's Ultimate Christmas, 10 p.m., BBC America See? He doesn't swear all the time.
