A Funny Predicament

I have a little pimple, a pimple on my b**t.
It's smarting and it's shouting and it terrifies my heart.
I try to wave the pain away by memorising Maths
But nothing stops the pimple from swelling very fat.

The exams are tomorrow and I am rather scared
My formulas are memoried, I'm pretty much prepared
But nagging worries dog my mind and foremost there is this:
One side of suffering b**k***es must give the chair a miss.

You can tell I'm taking a lot of study breaks.
