The curse started the day I watched my first Bills game, January 1, 1967. The Bills were coming off back-to-back AFL titles and were playing KC at the Rockpile for the right to play in Superbowl 1.
The Bills fumbled the opening kickoff which resulted in an early KC touchdown. It was all downhill from there, and the Bills lost 31-7.
If I had been smart, I'd have said "oh well" and given up football forever.
