A teacher asks the class to name things that end with 'tor' that eat things.
The first little boy says, 'Alligator.'
'Very good, that's a big word.'
The second boy says, 'Predator.'
'Yes, that's another big word. Well done.'
Little Johnny says, 'Vibrator, Miss.'
After nearly falling off her chair, she says, 'That is a big word, but it doesn't eat anything.'
'Well my Dad knows a lady named Nancy that has one and she says it eats batteries like there's no tomorrow!'"
