Late Show with David Letterman S21 E78 Donald Trump, Indianapolis 500 winner Ryan Hunter-Reay, Elizabeth Cook

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.
