Now here is something interesting. Someone was able to beat sober Biff. I thought it would be impossible. "In this video from the old adventure game Indiana Jones and the Last Crusade, I beat Biff the nazi w/o giving him a trophy full of ale and w/o cheating. As far as I know, I'm the first in history to do this. The original EGA version was released 1989, so it was about time I haven't counted how many times I needed to fight him to do this, but I think the number is between 15,000 and 50,000. Just the last about thousand tries were fought with this final strategy, which took me very long to discover."
