Here's one for free:
We have a friend who is allergic to full moons.
They make him come out in a terrible rash. A terrible hairy rash all over.
And his teeth start hurting and growing and getting sharper.
He’ll be in such pain that he rips his clothes but only so that his jeans would become shorts and his shirt would be ripped and open but not taken off.
He’ll also be in so much pain he howls (literally howls) at the moon for relief
Actually, now I’ve written this all down he’s clearly a werewolf.
I guess that explains who ate Tony.
