Seeing as we're smack dab in the middle of Shark Week, there's nothing like a good, 'ol fashioned shark-themed prank pulled on unsuspecting victims, is there? These patrons of a London seafood market aren't expecting this animatronic shark to suddenly come alive and jump at them while they're perusing the day's fresh catch. Come to think of it, I wouldn't either. I mean, I like seafood -- I just don't want it to eat ME, though.
