Little Johnny joke

[puternut]

Teacher asks class to name things that end with 'tor' that eat things.
1st little boy says "Alligator".
"Very good thats a big word".
2nd boy says "Predator... "
"Yes thats another big word".
Little 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 like anything!"

Teacher:

can you give me two examples...?

Little Johnny:
Your tits


not as funny, but as Little Johnny jokes go?
