Rainman 

A guy named Pat Burke. Every time he rides a motorcycle a rain cloud finds him. He's become a curiosity amongst midwestern riders, and those daring enough to ride with him. He hails from the land of the ice and snow.

I was going to go out riding but pat burke's curse struck, and now I'm bored. Damn you rainman!
