My School Cake ?

Butter, caster sugar, five eggs all mixed together
I’m making a sponge cake as light as a feather
Stir in self raising flower and a teaspoon of vanilla essence
My school cake should be absolutely quintessence

Bang it in the oven in a greaseproof dish
Oh I hope it hurries up and let’s hope it’s tasty, I wish
Well my cake smells lovely I really have to say
But hells teeth it’s been absolutely ages it is taking allday

Ah hells bells I cannot wait any longer so I take my cake out
I let it cool on the shelf then spread icing all about
I shake some rainbow sprinklers all over the top
Eeh what a messy worker I am 
I shall have to get the mop

So finally and at long last I get my knife
I cut it into ....”I DON’T BELIEVE IT”
“Ah well such is life”
As soon as I start to cut the cake
The dam thing isn’t cooked at all for goodness sake
Well yes It might look very edible and certainly very pretty
But I can tell you my school cake will taste shitty?
