Make an ominous beer glass right out of The Prisoner

On the episode of The Prisoner "The Girl Who Was Death," Patrick McGoohan stops by his local pub, only to learn — upon finishing his beer — that his drink's been poisoned. He saves himself by rallying like a champ.

If you wish to play similarly cruel pranks on your house guests, Sean Michael Ragan has a guide on how to etch such a glass over at MAKE. Please remember to not actually poison your guests or to sic mysterious balloon monsters on them.
