For the ones who don't know...
In the change over of the end of the second/begining of the third set Andy went to the lockers room and he took forever to come back. Lleyton was already waiting for him in the court and Andy came in running. So the ultimate question is what is it that he did that took him so long
He probably just changed clothes. Here they said that the lockers room is not too close to the Rod Laver so it probably took him long to get there and come back. But I bet he had to change his shorts, shirt, socks and shoes.
Of course he could have done it on court
that oooor he had diarrhea.
