I was winning 10-0 at halftime against a person who I really don't like, but because I'm a nice person I offered to switch to the losing side and let him be the side leading 10-0. He declined, obviously trying to be a macho.
So when I was awarded a penalty, he had a player sent off. He went crazy and as I went to take the pen (to make it 17-0) he bit my arm and then got me in a headlock. I reached out for my alarm clock, clubbed him over the head with it and he let go. I thought he was dead at first but he came round and I won 19-0.
