Dont' know if this one's been mentioned before.

No one died out there, as Boris Becker once said, but one of Karlovic's aces thudded so hard into the scoreboard all the numbers flew off. It was like a lorry shedding its load on the M1, and took almost as long to clear up.
This took place with something like ace No 10 in a total of 51, which does not include the 102 occasions (officially described in the match statistics as "unreturned serves") when Bracciali barely got a racket on the ball.
It was a tribute to the Italian's refusal to surrender (not to mention one in the eye for national stereotypes) that it took him the thick end of 4½ hours to break the Croatian's serve, but when he eventually did, it gave him the match 6-7, 7-6, 3-6, 7-6, 12-10.
If that’s correct, then Karlovic had 153 unreturned serves altogether. The ATP has him serving on 198 points, so that would come to an unreturned rate of 77.3%.
If the 102 unreturned include the 51 aces, then the unreturned rate would be 66.7%.
Anyway Karlovic held in his first 32 service games, a great run.
