Isner-Mahut in 2010 Wimbledon took 11 hours over 3 days and ended 6-4, 3-6, 6-7, 7-6, 70-68. It can't be repeated since they introduced tie breaks in the fifth set as a direct result of the travesty.

7 Days in Hell is another direct result of this match. :)

I mean, it could be repeated, but it would require an incredibly stable fifth-set tiebreak.
