I'm Irish and Scottish. I'm also possibly a descendent of the guy that shot Lincoln, but that's a different story.
That's almost as unlikely as me being related to one of the most infamous people to ever walk the planet. :|
My 6th grade science teacher tried telling us he was related to the guy that made Hershey's. We laughed and the kid with tourettes said some not nice things to him.
We had a rating system for his outbursts. We would hold up our ratings by holding up our hands with x amount of fingers pointing up. That got him solid 10s across the board.
