Late-night legend David Letterman crashed the Brooklyn Nets' media day on Monday ... and it was bad news for Kevin Durant, who was interrogated with a ton of tough questions!!
The former longtime "Late Show" host kicked off his round of Qs for the 2-time champ with quite possibly the hardest-hitting question in sports journalism -- asking about Durant's "KD" nickname ... which, of course, has always been a big mystery among fans.
"Why do people call you KD??" Letterman asked.
Durant explained the reasoning behind the moniker with unenthusiastic delivery ... and you gotta give him credit for having the patience to walk Letterman through that toughie.
