ABC Song

ABC song is a flash screamer created by AB user Bucketmouse, published for Albino Blacksheep in 2002.

The animation starts with a child singing the ABC song while the text in the center box morphs into each letter or line of the song. The animation appears normal until the child sings "Next time won't you--", where a masculine voice suddenly cuts in and yells, "Five!", while the screen flashes rapidly between black and red. During the flashing, a giant number 5 appears in the middle, flashing the opposite color from the background. The animation ends with a story made up by the creator about this happening during a syndicated airing of an episode of Sesame Street. The entire ABC song (without being cut off) can be found in the Flash file.
