Bob Davenport used to sing about an Agricultural Irish Girl - a completely different song, but I thought you might share it:

Twelve Stone Two

Well, I'll tell you, friends and neighbours, that I'm frightened for me life,
'Cos by this time tomorrow I'll be buckled to a wife;
An an agricultural Irish girl just twice the size of me,
And I'll tell you that I'm frightened what the consequence will be.

CHORUS: She's a fine, big woman, she's one you couldn't tame,
And by tomorrow morning she'll possess me name.
I feel so dreadful nervous that I don't know what to do,
For tomorrow I'll be buckled under twelve stone two.

She made me sit upon the bench, then sat upon me knee,
Imagine twelve stone two on a little chap like me.
She did all of the courting, I hadn't a word to say,
And like some helpless little lamb, I gave meself away. (CHORUS)

I'd like to break the contract off, but that would never do,
Me life would not be worth a jot, between meself and you.
I don't think she'll put me in a Breach Of Promise case,
But with her two big fists she'll put the breaches in me face.(CHORUS)
