Three Vampires on Halloween walk into a bar. The waitress comes up to them and asks them what they'll have.

The first vampire says with a Transylvanian accent, I'll have a glass of O Positive.

The second vampire says, I'll have a glass of AB Negative.

The third vampire says, I'm the designated driver. I'll just have a glass of plasma.


The waitress turns toward the bartender and yells, Gimme two bloods and one blood lite!
