A teacher asks the class to name things that end with 'tor' that eat things. 1st little boy says, "Alligator". "Very good, that's a big word".
2nd boy says, "Predator". "Yes, that's another big word".
Johnny says, "Vibrator, Miss".
After nearly falling off her chair, she says, "That's a big word, but it doesn't eat anything."
"Well my sister has one and she says it eats batteries!"
