A woman is standing in line at Costco holding a 50 lb. Bag of Purina dry dog food. Woman behind her says: 'Oh, do you have a dog?' No, she replies I'm going back on 'the Purina diet', 'How does the diet work? 'Oh, it's very simple, you just keep both pockets filled with the nuggets and when you're hungry you just munch on a few.'; although to be honest, I'm a little nervous about it, the last time I was on it, I lost 50 Lbs., but I ended up in the hospital with tubes comming out of every orifice. 'Oh my goodness, what happened? Were you poisoned? 'No she said. 'I was peeing on a fire hydrant and got hit by a car.'
