Mites and Lice. Most people are familiar with Dust mites and the common lice, while the dust mite does not acutally attack humans, there are many mites that can 'bite'. Most lice are scavengers, feeding on skin and other debris found on the host's body, but some species feed on sebaceous secretions and blood. Most are found only on specific types of animal, and, in some cases, only to a particular part of the body.
A duck walks into a bar and asks the bartender, Got any bread?. The bartender says, No.. The duck shakes his feathers, quacks, and leaves. The next day the duck walks into the bar and says, Got any bread?. The bartender says, No, and if you come back, I'll nail your beak to the bar!.
I think I'd better go out into the wide world, said the duckling. Suit yourself, said the hen. So off went the duckling. He swam on the water, and dived down in it, but still he was slighted by every living creature because of his ugliness. Autumn came on. The leaves in the forest turned yellow and brown. The wind took them and whirled them about.
