I'd say you've broken

Unfair assumptions I've started making thanks to Breaking Bad:

-All bald men cook meth.
-All goateed men cook meth.
-All khakis-and-ugly-jackets-wearing men cook meth.
-All Recreational Vehicle owners cook meth.
-Everyone who shops at Gen-X Clothing uses meth.
-Everyone who wears a beanie uses meth.
-Everyone who wears an ill-fitting black hat cooks meth.
-Everyone in New Mexico uses meth.
-My high school chemistry teacher might have been just as corrupt as I always suspected.

We're only part way through season 4, and I can already tell that I'm forming biases against mineral collecting car washes, and men named Gus.
