Folk poetry--does it have literary merit?

A poignant lavatorial meditation on the startling effects on the nervous system of Ruddles ale:

There's one thing the matter with Ruddles:
It gives me the shits and befuddles
My eyesight, my hearing, my balance, my steering
And leaves me here standing in puddles.

From Wiltshire:

Be I Berkshire?
Be I buggery! I comes up from Sarum*
I knows a gel with calico drawers
And I knows how to tear 'em
