Thompson is currently nominated for two Emmys — one for starring in his sitcom 'Kenan,' and another for 'Saturday Night Live.' He's been a cast member on 'SNL' since 2003, which makes him the performer with the longest tenure in the history of the show. Thompson talks about some of his most memorable 'SNL' sketches. He also talks about playing the Bill Cosby character Fat Albert in a 2004 movie, and later feeling disappointed by Cosby. "He was a prime example of a career that I wanted to have," Thompson says. "I felt super betrayed."Also, Maureen Corrigan reviews 'Agatha Of Little Neon,' a novel about nuns that she calls "sharp and, by turns, melancholy and wry."
