The victor of the longest match in the history of tennis made an appearance on ‘The Late Show with David Letterman’. John Isner defeated Nicolas Mahut in an eleven-hour match that covered a span of three days.

Monday night Isner did the “Top Ten” list on Letterman, listing the top ten things that went through his mind during the match, but with a comedic touch.

Overall it was a pretty entertaining list, should’ve seen the last one coming. Watch the video below.
