If you always wondered why Klingons have that ridged forehead, then wonder no longer. Just like a Trojan in a gold box, Klingons are ribbed for her pleasure.
And if you really had always wondered why Klingons have that ridged head, then I gotta question you’re upbringing. I mean, seriously! Who looks at a Klingon and thinks to themselves “Wow! That is an especially elegant example of evolution! But, what up with the ridged head..?”
