DALLAS—In the wake of the launch of "Doritos 3-Ds," Frito-Lay is experiencing a sharp decrease in sales of its original two-dimensional Doritos. "The public has gone wild for our revolutionary three-dimensional chips, which, in addition to the usual length and width, also possess depth," Frito-Lay spokesman Isaac Toomer said. "So wild, in fact, they have lost interest in traditional monoplanar snack chips." Toomer said Frito-Lay is now developing a highly theoretical "Funyuns 4-D." "One day, people everywhere will enjoy crispy, extratemporal Funyuns that intersect with an infinite number of parallel universes," Toomer said. "It will be a whole new world of non-Euclidean snacking."
