I do like me a kit-kat. The simplicity of the flavor works in great tandem with the crispy-breaky form of the bar. Snapping off a segment is just as satisfying as eating it and people who eat it like a regular chocolate bar are, without question, psychotic.
There's a huge variety of Kit-kats, too. Americans only have two or three, but Japan and East Asian countries have a boatload of flavors, including Apple, Red Bean, Green Tea and Strawberry (which is fucking amazing).
As a kid I used to break off a piece of that kit-kat bar and dip it into peanut butter. I haven't done that in maybe 20 years now so maybe it's not as good as I remember but I do remember it being tasty. Also there was always the moocher friend who wanted a stick after he or she watched you buy the thing.
I was always like "Fucker, I only have four of these! Get your own!"
