More liberal bias disguised as humor
When Ted leaves the hospital roughly half-way through the movie, we get a close-up of his rear bumper and the "Elect George Bush" bumper sticker.
Anybody who knows anything about movies and making movies knows that if it appears on the screen (and not on the cutting-room floor)then it is for a reason, and this scene gets quite a few seconds of screen-time.
It is a foregone conclusion that well over half of everybody working in the entertainment industry are Left-leaning, and while this is not a complaint (not here, anyway) it is just one more example of Leftist bias in Hollywood.
Aside from this, I enjoy this movie for the nostalgia factor, having graduated high school (like, in The Valley, ya know) in 1983.
