Three vampires walk into a bar. "What can I get ya?" asks the bartender.
"Blood," orders the first vampire.
"Make it two," says the second.
The bartender looks at the third. "What about you, buddy?"
"Plasma," says the vampire.
"Okay," replies the barman. "Let me make sure I've got this straight. Two bloods and a blood light."
