In its youth, the peacock has a magnificent tail that it uses to attract mates. The peahens pretend to be impressed and this ensures the survival of the species. Later, when the peacock reaches middle age, it looks in the mirror and wonders just what the hell happened.
The male salmon swims miles upstream against rapids and waterfalls to the same spot where it was born. There, the lucky survivors spawn, and within a few days, all their scales fall out, and they die. They try to tell their young, disturbingly called "fry," what's in store for them, but does anybody ever listen? No.
Each year hundreds of thousands of young monarch butterflies migrate from as far north as Canada to Cancun, Mexico, where they gather in thick lumps and the females display their wings for "Butterflies Gone Wild" videos. Their fathers stay behind and complain that in their day they were perfectly content to go to Fort Walton Beach, and these young ones don't appreciate how good they have it.
The male wood duck builds an elaborately domed nest of twisted twigs and leaves. After all the desirable mates have gone to better-looking ducks, it settles for what it can get and begins to raise a family.

Do you think twigs grow on trees?" and "What, were you raised in a pond?"
