Rugrats

At first, the title "Acorn Nuts And Diapey Butts" was used only in early schedules and press releases -- the actual episodes displayed only the titles of each part. But with the 8/4/2001 "movie", this title was used in the schedule. Also, in the "movie" version, there was only one title card, with the "Acorn Nuts and Diapey Butts" title, and one set of closing credits covering all 3 parts. Also, all the writers and directors are credited at the top of the movie. Finally, the titles of the 3 parts are not seen at all in the "movie" version.
