From this Times article, which restates H. Clinton's press statement about games and GTA:SA.
I can imagine how the National Institute on Media and the Family came up with this statistic.
NIMF: Billy, did you ever buy any Mature-rated games, especially one called Grand Theft Auto?
Billy: No, I never bought them. My mom and dad always buy them for me.
NIMF: No, Billy. Your parents couldn't have bought you the games, because we skinned them, drained them, and covered our expensive Italian sofas with them.
Billy: But...But I thought they were on vacation!
NIMF: No, Billy! They're dead! And you're statistic number one. Mark him down.
NIMF:Now what about you, Jessica? Did you ever buy Grand Theft Auto?
Jessica:No, I've only played it at a friend's house.
NIMF:Jessica, let's talk philosophy here. If you have played, for example, Game A, then you must have aquired Game A, correct?
Jessica: Well, not if my friend was the one who bought...
NIMF:No! Shut up! You bought the game, because you played the game. Are you a Philosophy major, you little wench?! I didn't think so! Mark her down!
Jessica: But...But!!
NIMF:Oh, and Jessica? You should tell us this friend's name as well, lest you'd like to have sofas as parents.
Scenario 2
NIMF:Jeff, have you ever played or purchased any Mature-rated games?
Jeff:I don't own a computer or Playstation, sir.
NIMF:Not relevant. Mark him down and kill his parents. I still have two uncovered pieces of furniture and you know Clinton won't sit on anything but flesh.
