It would be quite a project to watch every single "Simpsons" couch gag from the past 25 years.
That is, until now.
One very impressive person put together a quarter-century worth of the show's theme song closers and lined them up side by side in a YouTube video. You can now officially say you've watched the final intro moments of 554 Simpsons episodes.
YouTube user Omni Verse notes that that some of the gags repeat, and that in cases where there is no couch gag, something else from the intro is put in its place.
