Lyrics of 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)
