How do you like your pizza? Freshly baked, and steaming hot? Alas, the theory can only be applied to real pizzas we eat, and this American pizza joint learned it the hard way. Motorists driving past Casey's in Minnesota in the U.S. noticed a billboard featuring a 'steaming' hot larger-than-life pepperoni pizza. The faux pizza emitting smoke, while only for optics, scared motorists who made several panic-stricken calls to the police, that later tweeted saying 'there's no fire', and 'no need to call 911'.
