I'm right all the time so just refrain
disobedience and its ingredients I will just not entertain
don't answer me back and we'll be fine
the last word is mine.
So go on and do as you're told Mary, at once
I can't be Mary
cause Mary is dumpy why Mary is fat
Mary has freckles and sings like a cat, I'm not Mary.
Don't be stupid, of course you are
if I say you're Mary, then you're Mary
you don't make me budge, my word is law
Time's diminishing it we must be finishing
you are a pest and a bore
be off with you child, go sulk and whine
the last word is mine.
So go on and fetch my gloves and fan Mabel, at once
I can't be Mabel
cause Mabel is skinny she looks like a bean
Mabel is stingy she's ever so mean
I'm not Mabel.
If I say you are Mabel, then you are Mabel
you won't ever learn that I am right
you're unteachable, your brain's unreachable
in fact you're not very bright
