Dame, is your pan hot?
Your countenance suggests not;
I’ve come a-shovin’,
At this time of lovin’,
Tis but once a year.

So up to the flitch
and cut a gurt stitch;
If your hens don’t lay,
I’ll steal your cock away
‘Fore next Shrove Tuesday’s here.

Obviously it is about an itinerant coal man – “shovin'” being a contraction of shovelling, “time of lovin'” being a technical term for the fallow part of the year when no mining would be done for fear of kobolds and so coalmen would roam the land looking for any gainful employment. If she does not pay him for his trouble by darning his socks and some hard-boiled eggs, he wlll render her plumbing useless – this much has been preserved in your sanitised version – although given the primitive state it is in, she will only notice it in about a year, most probably when the cess pit begins to leak into the water table.
