Little johnny is at school one day and his teacher asks the class "Can anyone name a thing that eats other things?" The first little boy says, "An alligator, miss." "That's very good Kevin and a very big word too ... anybody else?" A liitle girl says, " Predator, miss." "That's another good one Susan." James puts his hand up and says, "A lion miss." "Very good," says the teacher. Little Johnny yells, "A vibrator, miss!" "No Johnny," replies teacher, "It's a big word but it doesn't eat anything." "Oh yes it does, my big sister has one and she says it eats bloody batteries."
