3x7 - Tales from the Crypt

A vampire is working at a blood bank as a night watchman. However, when the blood seems to be running low the vampire returns to getting blood the old fashion way. When the owner arrives at the vampire's lair he tries to black mail him, but as fate as would have it, the vampire's sexy secretary shows up and knocks him into the vampire's coffin. Some vampire hunters mistake him for the vampire and he gets a wonderful juicy stake.
