A teacher asked her class to name things that ended with 'tor' that ate things.

The first little boy said, "Alligator."
"Very good James, that's a big word."

The second boy said, "Predator."
"Yes, that's another big word Alan. Very well done."

Little Johnny says, "Vibrator."

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

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