Haha, almost like a true story
Last summer, we did a balloon ride with some (sadly) typical dutchmen celebrating holiday (e.g. lots of beer, barbecue and huge bellies...), and we had to divide the maximum # of passengers by about 1.5 (because of the average weight of the persons being ~120kg instead of ~80kg) :S It was hot that day too, so it was a really slow lift-off..
