Comedian-actor Adam Sandler dropped by the Light Show with David Letterman to perform an acoustic tribute for the soon-to-be-retiring host.
The tribute was equal parts hilarious and touching, as Sandler sang, “He’s leaving after thirty years/And you know he will be missed/If you like gap-tooth men in double-breasted suits/He’s number one on your top-ten list.”
Watch it below and have a laugh!
David Letterman’s final Late Show will air May 20, before Stephen Colbert takes over hosting duties.
