Vampires
Three vampires went into a bar and sat down. The barmaid came
over to take their orders.
"And what would you, er, gentlemen like tonight?"
The first vampire said, "I'll have a mug of blood."
The second vampire said, "I'll have a mug of blood."
The third vampire shook his head at his companions and said,
"I'll just have a glass of plasma."
The barmaid wrote down each order,
went to the bar and called to the bartender,
"Two bloods and a blood light!"
