Three vampires are sitting at a bar. Bartender asks the first one what he wants. “I
think I’ll have a glass of blood.” “Okay, what’ll you have?” he asks the second vampire. “That
sounds good. I’ll have a glass of blood too.” “And what can I get for you?” he asks the third
vampire. “I’ll have a glass of plasma” said the third vampire. “Okay,” said the bartender,
“That’s two bloods and a blood light, then.”
