An old parody

I wrote this parody of Housman's "Loveliest of trees" when I was an undergrad:

Sneakiest of Thieves

Sneakiest of thieves, the burglar now
Is hanging heavy from the bough,
And elsewhere in the woodland ride
Hang nineteen more caught at his side.

Now of the twenty thieves I know
All twenty hang here in the snow,
And take from twenty thieves a score
It leaves no thieves, and nothing more.

And since these lads gave less than took,
Men laughed to see them get the hook,
And through the woodland no one grieves
To see the boughs weighed down with thieves.
