Something really sweet I once read online: a bloke said that when he was little, his mother used to encourage him to eat peas by saying they were like zeroids. The result was, he ended up playing with the peas, instead of eating them.It is actually funny, the things parents resort to, in order to try to stimulate interest. I remember my mother telling me about how compasses worked, and I really couldn't give 2 hoots. She said "Compasses are very important," helping people to travel, and discover places like America. She added "And if there was no America, there'd be no Walt Disney!"
