When you visit an aquarium such as the one at Moody Gardens in Galveston or the Audubon Aquarium of the Americas in New Orleans there is a certain amount of trust. There is the trust that the creatures in the tank will stay in the tank. There is also a certain amount of trust that the creatures in the tank won't come after you outside of the tank.

The video above isn't from an aquarium. It's from the International Spy Museum in Washington D.C.

That should have given this museum-goer a clue that something was, pardon the pun, fishy.

The "aquarium" is actually a video screen. When a guest, such as our friend in the video, touches the screen it appears as if a giant shark swims into view. What happens next is the stuff that makes ordinary pranks epic.

I have to admit, I jumped the first time I watched the video. So, if you know someone who appreciates or is infuriated by a sudden scare make sure you send them this story.
