EA sucks balls again. Maybe if they spent more work on their games, less time DRMing, they would get more sales.
EA - you're stupid. You can't sue over an obvious parody.
Now, if someone CAME out with a video game like the one in South Park, had "EA" and "Tiger Woods", mass-produced / shared / sold such a game - then yes, EA and/or Tiger Woods would have a legal ground.
Otherwise, EA could sue David letterman, SNL, etc... and perhaps even open them selves to law-suits.
