Rickrolling is said to have begun as a spin-off of an earlier prank called "duckrolling"., which was when a link was supposed to lead to a picture or news story but would really link to an edited picture of a duck on wheels. The victim was then said to have been duckrolled. The first instance of rickrolling happened in May 2007 on the 4chan video game board, where a link to the video was said to be a copy of the first trailer for Grand Theft Auto IV. The joke was confined to 4chan for a short time.
