Have you seen Netherbeast, inc? there's a scene where the CEO is having a discussion with another employee, and there's a dead guy with a steak through his heart.
The employee finally asks what's up.
well Mike was a vampire.
how do you know?
well he had blood on his shirt... you'll have to trust me (points at huge blood splatter from stake).
and the employee grows increasingly incredulous at each of the answers
"well he died when i drove a stake through his heart" so would anyone.
"well he never left the office." neither do you.
"well he recoiled when i shoved a cruxifix in his face" he was jewish
did you try silver bullets? "that only works on werewolves" and then the CEO cocks a gun and says he needs to see accounting.
same energy. well done. i like how it was simple, clean. with plenty of jokes.
