Why I oughtn't be allowed out on low sleep

I was reading Charles Petzold's blog again, and it was talking about Desk Set, which is my favorite movie of my mom's favorite movies (creepy yet?), and I realized that the reason I think Spencer Tracy is cool is because in that movie he plays a computer salesman. Also, it's definitely the best appearance of a computer in a movie ever, including 2001, which is great, but Hal would never really do that, and WarGames, because, seriously, WOPR would have just realized that the human that told it to play Tic-Tac-Toe was a Communist and needed to be killed. SO unrealistic.
