Martin paid homage to Letterman on The Late Show on CBS Friday night, with a video suggesting all the things Letterman could do during his retirement.
Aside from pill-sorting and chowing down at Golden Corral, Martin said Letterman will "vacation alone on the beautiful beaches of Newfoundland." [Martin may need some work on the pronunciation.]
Letterman's last night on the desk is May 20. He will be replaced by Stephen Colbert.
