thing that end with - tor

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 Leo says, "Vibrator, Miss."

After nearly falling off her chair, she says, "That is a big word, but it doesn't eat anything."

"Well my sister has one and she say
 it eats batteries like there's no tomorrow!"
