Hopefully somebody took a life insurance policy out on grandma before deciding to play this prank, because they nearly gave her a heart attack.
While at the International Spy Museum in Washington, D.C., the grandkids decided to play a prank on their grandmother by having her tap the shark tank aquarium glass.
The aquarium was really a very hi-def TV screen that played a video of a great white shark lunging at the woman.
“Oh my God!” the grandmother yelled. “You scared the crap out of me!”
