1 - My dad didn't do jack and I lost. My dad doesn't care about me.
2 - My dad helped and we lost. It was fun and he cares about me, but he's an idiot that can't even out-race kids.
3 - My dad did all the work, wouldn't let me touch it. We won, and it rocks. But I'm going to grow up to probably be unskilled and end up moderating a message board.
It's a lose/lose/lose.
Schedule an awesome vacation so you'll have to miss the derby.
