Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the King's horses and all the King's men,
Couldn't put Humpty together again.

They called a doctor from the town.
To come and fix poor Humpty's crown.
He put a stitch in Humpty's leg.
And bandaged up poor Humpty's egg.

He used some tape and then some glue,
And Humpty's now as good as new.
