Jack oh Jack

Where are you Jack? (Co-winner, Writer's Cramp Contest, 2021 Oct 29)

Jack oh Jack, Where are you Jack?
Jack oh Jack, We want you back.
Did the horseman take you Jack,
To replace his head a lack?

Bada bingo bada bing,
Who za do za such a thing?
Catch the crook and make him sing.
Bada bingo bada bing.

Search we high and search we low,
Did we find him? That be no.
Look again and go so slow,
Everywhere a no no no.

Slow ... we ... go ... and try and hope to learn,
While our minds are filled with frothy churn,
The myst'ry does continue to spurn,
WHAT HAPPENED TO THE JACK O'LANTERN?
