Looney Tunes is known for providing tons of laughter and the overlooked 2001 cartoon The Matwix lampoons The Matrix (1999) in a family-friendly and looney way.

Elmer Fudd (Billy West) gets a phone call from Bugs Bunny (also Billy West) saying that the world is all false except for two donuts he is holding.

I can't tell you the rest because it will spoil the short film that is now on YouTube. The Matwix has you, doc and it is great!
