"Kohl, a 26 year-old Austrian from Klagenfuhrt, waited a long time in the doping control truck and missed the helicopter that could get him off the mountain quickly."
"It’s impossible to mask an average dose of EPO in the first three days after injection. Unless you can thin your urine. That’s what I saw at the Tour two years ago, as an observer for the UCI. In one particular team none of the riders managed to provide a urine sample for an hour and a half after the race. They couldn’t, so they had to drink a lot. All of them from the same team, very strange. But coincidence? Probably not. Because there are two ways to thin your urine: either you take diuretics, but those are on the list, or you drink litres of water. A watery urine makes it harder for us. A few riders of that team tested positive later on, but you’ll understand that I can’t name the team."

After Rasmussen won his TDF stage in 2005 he also took forever to give his urine sample. I think he nearly missed the plane that had to transport the riders before the rest day or would have missed it if it hadn't been delayed. It was somthing like that.
