There are these 3 vampires. The first vampire walks into a bar and says, "Bartender, give me a shot of blood." The bartender gives him the shot of blood, the vampire drinks it, and leaves.

The second vampire walks into the bar and says, "Bartender, give me a shot of blood." The bartender gives him the shot of blood, the vampire drinks it, and leaves.

The third vampire walks into a bar and says, "Bartender, give me a shot of water."

The bartender says, "Why do you want a shot of water?"

The vampire pulls out a dirty tampon and says, "Tea time."
