David Letterman's late night show

It has been quite sometime since I last watched the Late show with David Letterman. I remember many, many years ago, it was one of the rare late night American shows that I used to watch, so do my friends, when we were much younger. Sometimes, I may not understand American's humour well, but, it was still funny, you know? It finally ended, David will no longer appeared on his show anymore, he will be missed, definitely.
