Henry, the Worm
Sittin’ on the fencepost,
Chewin’ my bubblegum,
Playin’ with my yo-yo, woo-woo!
When along came Henry the Worm,
And he was this big (show with hands, each verse the hands get wider apart, until fifth - then the hands are tiny).
And I said, “Henry, what happened?”
first time: “I ate my brother.”
second time: “I at my sister.”
third time: “I ate my father.”
fourth time: “I ate my mother.”
fifth time: “I burped.”
Note: I've also heard this song use the name "Herman" and "Hermie".
