Krazy Kat is a character in the comic strip of the same name, written by George Herriman, starting initially as a side strip to The Family Upstairs, and then as a fully fledged strip in 1914, until Herriman's death in 1944.

It concerns an unrequited love-triangle between Krazy, Ignatz mouse and Offissa Pupp, and lots of brick-heaving.

A work of genius, in my opinion
