As families gather for Thanksgiving, Nickelodeon offers a silly treat with intergenerational appeal. Former “Kenan & Kel” stars Kel Mitchell and Kenan Thompson return to Nick for a repeat match on a special episode of “Double Dare” (7 p.m., TV-G).
Actress and digital star Liza Koshy serves as host, with original host Marc Summers along for color commentary. Look for Lori Beth Denberg (“All That”) as well.
Aimed at kids, the green slime-centric obstacle course game show has been around long enough to have entertained many of today’s parents. “Double Dare” premiered on Oct. 6, 1986. Summers hosted the series’ original run until it went off the air in 1993. At the time, it was one of the most popular original daily programs on cable television.
- Proof that not every bird is a butterball arrives on “NOVA” (8 p.m., PBS, check local listings). If asked to bet on the world’s fastest animal, many might suggest some swift jungle cat. But the prize goes to the peregrine falcon, capable of diving at nearly 200 mph nearly three times the speed of a sprinting cheetah.
“NOVA” explores how the falcon was driven to near extinction by the use of the DDT pesticide, but has since flourished on every continent. It seems equally at home in the wild and perched atop urban skyscrapers. We follow three native Chicago falcons from birth (or rather hatching) as they take their first awkward adolescent flights and eventually learn the skills that make them some of the world’s best hunters.
