A Canadian couple is making money after changing the name of their breakfast cereal to 'Holy Crap'. Brian and Corin Mullins developed their gluten-free, vegan, organic cereal to address Mr Mullins' allergies. It was originally called 'Hapi Food' cereal and sold locally on the Sunshine Coast, British Columbia But after one of their very first customers said: "Holy Crap... this is amazing!", they changed the name to Holy Crap. Sales increased 1000% - from ten bags a day to over one hundred.
