Late Show with David Letterman S18 E25 Ed Helms, Ted Alexandro, Steel Magnolia

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.
