Herman the Worm

I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big
I asked, "Herman, what happened?"
And he said, "I swallowed one grape"
I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big
I asked, "Herman, what happened?"
And he said, "I swallowed two apples"
I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big
I asked, "Herman, what happened?"
And he said, "I swallowed three grapefruits"
I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big (how big?)
I asked, "Herman, what happened?"
And he said, "I swallowed four cantaloupes"
I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big (how big?)
I asked, "Herman, what happened?"
And he said, "I swallowed five watermelons"
I was sitting on a fence post
Slapping on my left knee
Chewing on my bubble gum
Chomp, chomp, chomp, chomp
Playing with my yo-yo
Do op, do op, do op, do op
And watching the birds fly by
And then along came Herman the Worm
And he was this big (how big?)
I asked, "Herman, what happened?"
And he said, "I burped"
