The Child Abduction meme was created in /b/ when a /b/tard posted a picture of his television with a picture of Bender from Futurama on the screen, which displayed the words "Child Abduction" as closed caption text. The picture was an instant hit and resulted in hundreds of shoops all over 4chan, including Bender attacking different children with the words "Child Abduction" pasted on. The shops were not limited to Bender and included many other people that might be considered "child abductors," e.g. Cockmongler. It turns out the "Child Abduction" text was sent out by an Amber Alert and wasn't a closed captioning error as the OP previously thought.
