Actually it's my fault. When I was 17, the Cowboys were clinging to a 20-17 lead in Super Bowl XXX. The Steelers were driving. I was holding the TV remote in a death grip and remember saying something like "Just let them win this Super Bowl and I don't care if they ever get another one".
A few minutes later Larry Brown picked off Neil O'Donnell, Emmitt scored, and Dallas won 27-17.
If there was a higher power listening to me last night, I really didn't mean the part about never getting another one. Please let me retract it.
