The One Who Invented Trick or Treat 

Yes, I invented "Trick or treat"
So you could fill your mouth with sweets—
Candy bars and lemon drops,
Marshmallows and Tootsie Pops,
Butterscotch and bubble gum.
Hold out your hand—they’ll give you some
Chocolate kisses, Jujubes,
Sourballs and jelly beans.
Have a cake—some cookies too.
Take a couple—grab a few
Peppermint Sticks and Mary Janes, 
Licorice whips, and candy canes,
Slurp some soda, munch a pie,
Don't let those M&M's go by,
Chew that toffee, munch those treats,
Get that caramel in your teeth.
Then come see me, I'll be here- 
I'm your friendly dentist, dear.
