Show of the week: Carol Burnett: The Mark Twain Prize

A bright week for comedy on television hits its apex with this two-hour taped special honoring Carol Burnett. Burnett’s self-titled sketch show was arguably the funniest hour on TV for much of its 1967–78 run, as numerous highlight clips suggest. At 80, Burnett still has the impeccable comedic timing and endearing awkwardness that made her a queen of Saturday prime time. Stars on hand to toast her include former cast mates Vicki Lawrence and Tim Conway. Says Tina Fey, “I love you in a way that is just shy of creepy.” Sunday, Nov. 24, at 8 p.m., PBS; check local listings
