A vampire walks into a bar, “Pint of blood, landlord.” he says. The barman gives him his order.
A second vampire walks into the bar, “Pint of your finest blood, please.” he says. Again, the barman pours his order.
A third vampire walks into the bar and says, “A mug of hot water, barman.”
The barman looks puzzled at the vampire, and asks, “Why would you want that? We serve the finest blood in all town!”
The vampire then held up a used tampon and answered, “I’m making tea.”
