Beside the health benefits, I agree, it's not chili without beans. However that does remind me of a scene between Willie Nelson and Rip Torn in Another Pair of Aces where they're eating chili around the fire and Willie mentions - as they're in Texas - that he hears that northerners put beans in their chili and Rip Torn replies that he believes he would have to kill the man that put beans in his chili.
“That's it. You people have stood in my way long enough. I'm going to clown college!”
