"Krazy Kat" is one of the all-time classic comic strips. By George Herriman, it's surreal, poetic, funny, touching, violent, and just plain weird.
It's basically a Funny Animal strip about unrequited love... or maybe unconditional love. Whatever it's about, there's a triangle of love/hate between the innocent Krazy, the mean-spirited Ignatz, and the gruff Officer Pup. The strip long been a favorite of mine. Here are a couple random samples of the series. (Click on the images for readable versions.)
Here's a fun animation that gives the gist of Krazy Kat and his world.
