Late Show with David Letterman S21 E39 Mary-Louise Parker, Lenny Marcus, Joan Jett & the Blackhearts

David Letterman uses mature humor to appeal to his audience in this weeknight series, which gets its music from a house band led by Paul Shaffer. Among the show's most-famous segments are the Top Ten List and Stupid Pet Tricks, the latter of which subsequently led to an additional recurring segment called Stupid Human Tricks.
