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."
