Tom Selleck on Letterman, May 23, 1985
By request. Tom Selleck's first appearance on Late Night. At the time, his popular television show "Magnum P.I." had just ended its fifth season, and in the same time slot was the network's breakout hit "The Cosby Show," just ending its first season. Thus Tom's Cosby joke in the Cold Open, which is the first item in the subsequent conversation with Dave.
