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!.
The second man drops to his knees and starts sucking on the hot-dog. You faggots! screams the bartender. Get the hell out of here!. They run out and go to another bar and order drinks and when the bartender asks for money, the first man unzips his fly, and the second man drops to his knees.
