Is there anything so disgusting tasting as a food that isn't what you thought you were eating?

for example, I am eating some baked cheddar and sour cream chips right now, but I thought they were baked doritos, and every time I take a bite, I try to remember that I am not eating doritos, yet every time I expect it, and thus I cannot enjoy these chips.

And that means I will consume the entire bag hoping to find out how to enjoy them without actually doing it. dangit!
