"Tortilla Flat", by John Steinbeck, is basically a West-coast 1920's "It's always sunny in Philadelphia".

Someone else seems to agree with me.

Both are about five self-centered, unambitious, working-class, heavy-drinking friends.

Both are raucous, alcohol-fueled, dark comedies.

Both are awesome.

Also, Tortilla Flat was the top-selling book in America during The Great Depression. "Always Sunny in Philadelphia" is the longest-running live-action sitcom in US TV history.
