What I learned over my summer vacation is that the saddest, most horrible animal on the earth is the halibut. If you see a halibut, it is okay to give in to your impulse to cry, as there is no sparing the feelings of such a dejected and god-forsaken creature.
A fact about the halibut: The halibut begins it's life swimming like a normal fish. Upon maturation, the halibut's eye fucking migrates to the other side of it's body. It's eye fucking migrates. I do not think one can discuss this terrible metamorphosis without the adjective "fucking." It's just that unreal and unsettling.
I hope I never meet a real-life halibut as long as I live.
