Three Vampires

Three vampires go into a bar. The bartender asks the first one, "What can I getcha?" The first vampire replies, "I'll have a pint of blood". The bartender then asks the second vampire, and he too orders a pint of blood. The bartender turns to the third vampire and asks, "What about you?" The third vampire says, "I think I'll have a pint of plasma." The bartender says, "OK, so that will be two Bloods and one Blood Lite."
