The Simpsons: Flickbook

This digital flickbook covers the longest ever "couch gag" (The ever changing bit at the end of every Simpsons intro), often called "The Evolution Of Homer".

It featured in episode 16 of season 18 titled "Homerazzi" and is 1 minute 23 seconds long - the entire intro, couch gag included, is usually only no more than 1 minute 30 seconds!
