19. Alex Rodriguez
Cockiest Quote: "When people write [bad things] about me, I don't know if it's [because] I'm good-looking, I'm biracial, I make the most money, I play on the most popular team..."
Oh, A-Rod. He's without a doubt one of the most annoying people in sports history and has the track record to prove it. Even as a young'n in Seattle Alex always put himself above others, he reportedly would ask dates: "Who's hotter, me or Jeter?" Then when he went to Texas and received the richest contract in baseball history that ego ballooned to unseen heights. Take that feeling you have on payday and multiply it by about 250,000. Yeah, that's how dude is feeling-every day. Excuse us as we try to figure out where things went wrong in life.
