In case you hadn't heard, "John Isner finally brought an end to the longest match in tennis history today as he broke the serve of Nicolas Mahut to secure a 70-68 victory in the deciding set of their first-round Wimbledon encounter." That's not a set of tennis; that's a basketball game!
Update: the LiveBlog from the Guardian puts it much better:
The Isner-Mahut battle is a bizarre mix of the gripping and the deadly dull. It's tennis's equivalent of Waiting For Godot, in which two lowly journeymen comedians are forced to remain on an outside court until hell freezes over and the sun falls from the sky.
Pretty much, yeah.
