From Torrent Freak:
This week's episode of Family Guy included a clip from 1980s Nintendo video game Double Dribble showing a glitch to get a free 3-point goal. Fox obtained the clip from YouTube where it had been sitting since it was first uploaded in 2009. Shortly after, Fox told YouTube the game footage infringed its copyrights. YouTube took it down.
