Five little babies bouncing in a crib
One fell out and lost her bib!
Daddy called the doctor and the doctor said,
No more babies bouncing in the crib!
(I know if doesn't rhyme, but eh. Who cares?!) Wait! Edited to add:
...Daddy called the doctor who was not glib)... I just thought of this, and I'm definitely going to use it, because: what a great vocabulary word!
