America's Funniest Home Videos

ABC | 7:00 pm

If it's not broken, don't fix it: That must be a basic principle for this show, as host Alfonso Ribeiro returns to open Season 32. The format couldn't be simpler, with Ribeiro introducing a diverse assortment of video clips that show humans and animals at their unguarded best — or, even better, their embarrassing worst. Whatever the reason, this show is the longest-running primetime entertainment series in ABC history, and it also leads the pack in terms of family "co-viewing," with parents and kids watching together.
