Isn't this a small world? I found that joke on fark.ru two weeks ago, in Russian, and I translated it into Serbian for some of my friends... and here it is now in English (with names removed - not Alyosha and Vasya, just 'husband' and 'drunk'). Now I wish I could trace it.

The fastest turnover for a joke was three hours, on a trip. Roommate and I heard a joke the evening before; in the morning told it to a friend while we were waiting for the bus to take us to the airport; after two hours of flight someone tried to tell the joke to us. But there were only about thirty of us in the group.
