Or, "fun with natural selection"
Fish are crazy, no?
Take this one:
Dr Norman was also fond of the fangtooth, "one of the most savage-looking of all the deep-sea fishes". Two sharp teeth poking out of its bottom jaw slide into pockets in its head, saving the fish from stabbing itself in the brain.
How many drafts you suppose they went through before they got that one right?
I'm always in danger of stabbing myself in the brain too - but that threat usually comes from either my razor sharp wit or a suicidal urge that creeps up whenever I read bills from certain members of the California State Legislature.
