Another record was broken on a crazy afternoon at the Crucible, as Mark Allen and Wu Yize contested a 100-minute frame in their World Championship semi-final.
Wu would win it, eventually, after requests for a re-rack, protestations from Allen, and a number of audience members desperately pleading to go to the toilet.
In the end, with the score 7-7, the players were hauled off not long before 7pm with only six of the scheduled eight frames played, that after over four hours of snooker which shifted from the sublime to the ridiculous.
The sublime came from Allen who began the session trailing 6-2 but surely ended it the happier of the two men, his comeback kickstarted by winning a couple of scrappy frames to start, the second on the final black.
Moments later the Northern Irishman compiled a flawless total clearance of 145, the highest break of the tournament so far, and after controlling the following frame, he added another century to make it five on the spin.
What proved to be the final frame of the afternoon was described by Stephen Hendry on the BBC as the 'dark side of snooker', the black hanging over the bottom corner pocket and converged by a pack of reds for what seemed like an age, until the deadlock was broken by Allen when he opted to purposely foul the black into the pocket.
Nevertheless, Wu did well to hang tough, battling his way into the ascendancy and then escaping from a terrific snooker laid by Allen on the final pink to ensure he had something to show for his afternoon's toil.
The match resumes at 10am on Saturday.
Higgins edges ahead of Murphy
John Higgins and Shaun Murphy moved at a faster pace in their semi-final, with the veteran Scot carving out a 13-11 lead ahead of Saturday afternoon's concluding session.
After the first eight frames were shared on Thursday, and the second eight on Friday morning, Higgins made his move late in the third session, putting together breaks of 63, 70 and 101 to win three of the final four frames of the night.
Those final four frames will have stung Murphy who made the running in a number of frames early in the session, only to make mistakes at key moments.
Higgins picked his pocket in the 19th frame when winning the game on the final pink following a brilliantly-laid snooker, and Murphy was left to rue another miss, this time along the bottom cushion, when trying to offer the perfect riposte in frame 21.
The 2005 champion did have time to register his second century of the match soon after, but Higgins' impressive late burst means he is now only four frames away from a ninth Crucible final.
