>Interestingly, I've heard this joke when I was on second year of maths (from a chemistry student, though), and it featured Winnetou, Old Shatterhand and - guess who - Chapayev. The guy just said "and... don't ask me why, this is how I heard it... Chapayev".

At some point back in the Soviet Union times there were a hundreds jokes about Chapayev and his "adjutant" Petka (Петька). I guess somewhere on the way to you Petka has been replaced with Old Shatterhand. :)
