My Spoiler Policy According to Sheldon Cooper:
Stuart: Here, Sheldon, I pulled the new Hellboy for you. It's mind-blowing.
Sheldon: Excuse me! Spoiler alert!
Stuart: I didn't spoil anything.
Sheldon: You told me it's mind-blowing, so my mind is going into it pre-blown, and once a mind is pre-blown, it cannot be re-blown.
