Did the original scene have a swear word in it or something else that might need to be edited out? Maybe they filmed an alternate scene w/o the part needing edited and that’s what the show on TV.
I just compared my DVD to this YouTube clip, and it’s indeed changed. I had a theory similar to Bob Ducca’s (notice that they did alternate takes so “holy shit” could become “jeez louise,”), but all the handwriting is exactly the same, except for the 2 changed digits.
Wikipedia led me to this article, which indicates that numbers above 555-0199 have been available for real since 1994, but are difficult to activate.
I heard comedian Tim Wilson on the radio say that they draw the line at actual body parts. That is why you can use made up things like ass-bag but not real ones like asshole.
