Here's a classic entertainter that's still working today here and there.  Bob Newhart who been doing comedy for a long time has appeared on the Dean Martin show a bunch of times and today I'm sharing a couple of sketch's that they've done together.

The first video is Bob Newhart returing a wig that he bought in which Dean can't stop laughing.  The second video is Bob and Dean at a nudist colony.

You can see Bob in TNTs The Librarian movies.
