Reverse voodoo?

Do you think if all Reds fans went and bought one of these banners that the Reds would win the World Series, immediately putting the banner out of date? You know, how you think about something and then it doesn't happen? Or you think something won't happen, then it does? Like when you bring an umbrella somewhere because you know if you don't bring one, it will rain? So we buy these because we know the Reds won't win the World Series so we'll be able to enjoy our not-outdated banner, then they do win? Am I making sense here?

We have to try everything, don't we? :)
