Sparky's Alligator Song

Mom: (in doorway, to Gerald, who is in bed) Goodnight, dear.
Dad: (in doorway, too, to Gerald) Goodnight, Gerald. (and to the dog, on the floor beside the bed) Goodnight, Sparky.
Mom: (to Sparky) Goodnight, Sparky.
Gerald: Goodnight, Mom. Goodnight, Dad. Goodnight, Sparky.
(Door closes and lights go out. Sparky jumps up and runs to the foot of the bed where he makes a huge shadow of an alligator on the wall)
Sparky: (singing) Imagine me an alligator! (chorus in background sings "Alligator!")
Gerald: MOM! There's an alligator in my room!
Mom: (coming in; Sparky dashes back beside the bed) I don't see an alligator.
Gerald: Sure, it's not there now, but when you turn out the light, it's there!
Mom: Go to sleep, Gerald. It's just your imagination.
(Door closes and lights go out. Up jumps Sparky.)
Sparky: (singing) Sweet potato! (chorus: "Alligator!") I was lookin' --
Gerald: MOM!!!!!
Mom & Dad: (opening door; Sparky of course returns to spot) What is it?!
Gerald: The alligator! It's back!
Mom: (leaving) Go to sleep, Gerald.
(Sparky resumes his song)
Sparky: (singing) And you came by for me to munch ya!
I'm afraid of gettin' thinner
Won't you please become my dinner --
Gerald: (peeking over the end of the bed) Sparky!!! It was you all the time!
(Sparky blushes and goes to sleep)
Mom: (from hallway) What is that singing?
Gerald: Oh, nothing, Mom. Just your imagination. (grins)
