Tributes to David Letterman, Part 11 of 31: Bruce Willis 1985, 2015 

To commemorate the 5th anniversary of Dave retiring from late night television (his last show was on May 20, 2015), I've put together a series of "first and last" appearances, the latter paying tributes in their own ways to the last giant of late night (h/t Jason Zinoman).
