To sir, with love!
Yesterday, David Letterman stopped by Live! to big Regis Philbin a fond farewell after 17,000 shows! (That's what the man said!) As the funny and memorable interview came to a close, David unexpectedly stood up and kissed Regis goodbye on behalf of us all who will miss him so.
Or, after all these years, he's just been waiting for his moment to finally express his true feelings and he just went for it! Kelly Ripa did scream something about a probing tongue! LOL!
Check out the moment in the video (above)
