How to get one good mum

Maxime ma'am says moon is mum of stars.
Molie says "mum made me mocktail".
Wicked Wompey wants his mum gone.
I wish I had a mum.

Joe, why do you say she's worthless ?
But I've told that she's greatness.
I've had not had that special gift
I wish I had a mum.

Dad, why do you say loads don't have ?
Mrs. Davey says all do have!
Even my puppy Poper plays with his mum
I wish I had a mum.

Uncle Tom in tomato stores
Says he sells all and all.
I'll get my best in coming term
I'll get my dad to buy one good mum.
