I'm not even much of an Earnhardt Jr. fan (always a fan of his Dad) but when I saw that he was going to drive his father's car, there was no way I would miss the race.
When he won, I jumped up and down like Dale Sr. himself had just won the Daytona 500 all over again. My dad thought I had went crazy.
But since this thread is Jr. winning in his dad's car... I have to put my favorite quote by The Intimidator himself...
2001 Daytona 500 after qualifying, interview with Jr. and Sr. -- Dale Sr. ", You know, We may have the same name, but I don't want to be known as Senior... it makes me feel like an old man."
