Three vampires walk into a nice, dark, dive bar. The bartender looks at them a little sideways, but decides to serve them anyway. “What’ll it be, boys?”

The first vampire says “I’ll have a Blood!”

The second vampire says “Mehh, I’ll also have a Blood.”

The third vampire says “I’m watching my figure, I just want plasma.”

The Bartender smiles and says “Got it. Two Bloods, and a Blood-Light.”
