“LIVE WITH REGIS AND KELLY” (9 a.m., 21 WFMJ-TV): OK, so he’s not Oprah, but Regis Philbin is, nevertheless, a heavy hitter in the world of daytime television. And now, after 28 years of hosting morning chat fests, he’s calling it quits. “Live” will fete the lovable crank throughout the week with some of Reege’s favorite guests and friends, including David Letterman, Donald Trump, Don Rickles, Jimmy Fallon and former sparring partner Kathie Lee Gifford. The shows also will feature musical tributes each day with the likes of Tony Bennett, Josh Groban and others. And on Friday, Philbin bows out for good in an hour that producers promise will be jam-packed with special memories and surprises. Philbin, 80, also will get a prime-time send off (8 p.m. Thursday, ABC) when Katie Couric interviews him.

“Swampsgiving” (9 p.m., History Channel): In tonight’s “Swampsgiving” special, we get to see how the Louisiana gator hunters of “Swamp People” celebrate the holiday. Warning to nature’s critters: Run for your lives!

“The Office” (9 p.m., nbc): On “The Office,” Andy (Ed Helms) hopes to inspire and motivate the troops by taking them to Gettysburg. We predict an epic failure.
