I like the word poetical. While it's not an example of a malaprop, it reminds me of Norm Crosby. Does anyone remember him? At any rate, in honour of words ending in 'al', here's...
Ode to a Testicle
The doctor said it's mystical
The nurse was ever practical
My friends were always cynical
I have an extra testicle
In school they called it magical
The tailor called it tragical
The girls all had a festival
I have an extra testicle
The jealous called it minuscule
Their thoughts so very clerical
It's all extremely medical
I have an extra testicle
A few have said it's radical
And all have called it laudable
It's totally symmetrical
I have an extra testicle

Stephen, that is,.................comical.
