My personal favorites:
7. People who swear at the players. How badly has your life gone that you feel compelled to come to the park and yell obscene words at somebody playing baseball? Trust me, when the player goes back to his huge house and his insanely hot wife that night, you calling him names doesn’t make him feel bad.#7, is unfortunately me, so I apologize to anyone I've sat next to, or near, when viewing a New York Mets game. I cannot agree with #8 more. I despise The Wave in every way, and refuse to participate in it, ever.
8. People trying to start The Wave. The Wave is a plague on sports. It’s 50,000 people saying, “Look at us, we’re all mindless and we don’t care about the game.” Thankfully Yankee Stadium is largely Waveless.
I also don't like those two goofs in electric blue suits and sunglasses with the bald heads that wander the stadium. No one likes you, so just stop. Don't get me wrong, I absolutely love Cow Bell Man, but that is because he's cool, those bald guys are just creepy.
