This may be common knowledge, but for SIMPSONS fanatics, I mention the following:
If your tv has closed captioning, I recommend turning it on sometime when you watch THE SIMPSONS.
The closed captioning must be done from the last version of the script, and often times, the punchlines to jokes are changed. So there'll be a whole different punchline to some of the jokes with the closed captioning. This happens just about every episode, several times.
Sometimes, the original joke (on the closed captioning) is funnier than what was finally used on the audio. ---- Just as one recent example (not a particularly funny one, but it illustrates what I mean):
There was a recent episode where Homer picks up the phone, and says, "I'm calling [such-and-such]."
Then the operator responded, "Pay your phone bill first!"
But on the closed captioning, it was LISA: "Dad, I'm on the phone!"
