Humpty Dumpty

They just finished a nursery rhymes unit at David's preschool.  Here is what I have been hearing for three weeks now:

Humpty Dumpty sat on a wall,

Humpty Dumpty had a great fall.

All the loaders

and dump trucks

and cranes

and cement trucks*

couldn't put Humpty together again.

*Dad, I'm sure what he really means to say is "ready-mix concrete trucks."
