Donovan McNabb didn't realize that you could have a tie game in the NFL until yesterday when his game finished in a tie. Until the final play of the game, in which he was wondering why they coach was calling a Hail Mary pass, he thought that they were going to go into a 6th quarter.
Then, he said something to the effect of, "Well, I'd hate to see something like that happen in the playoffs or the Super Bowl," thus not realizing that there are no tie games in the playoffs. This second thing is clearly much stupider even than the first.
On SportsCenter they played calls from Philadelphia sports talk radio and they were killing McNabb. It was amazing. This one guy calls and says something like, "Here's McNabb who figures that the Super Bowl is tied after five quarters and they just shut it down and hand out two Lombardi Trophies." I guess it's like the Special Olympics.
