Five Grouchy Monsters

Five grouchy monsters behind my closet door
One hears his mother call and now there are four.

Four grouchy monsters growling at me
One leaves to have dinner and now there are three.

Three grouchy monsters making a hubbaballou
One must go wash his face and now there are two.

Two grouchy monsters not having much fun
One decides to brush his teeth and now there is one.

One grouchy monster feeling all alone
His eyelids feel they weigh a ton and now there are none!
