Umm...do Funyuns count?
Wait...no...on second thought...Art's & Mary's jalapeno kettle chips. Those are godly. Those things can light your mouth on fire (seems to vary from bag to bag), but you just can't stop eating them.
I think they're just regional, though. There's only a few places here that stock them, and they're made in Kansas. But good lord, they're amazing.
