It depends on who you ask and when: the barzelletta was a 15th-16th century Italian poem created mostly as secular song, meant to entertain with rhyme, pun, and word play while perhaps offering some didactic lessons. Many forms were trochaic tetrameter, which I used here.

Barzelletta for the 4th of July

“Why this song on ‘Pendence Day, lad?
Form’s found first in ancient Roma
Fifteenth cent’chry wordplay fad
Gets you now no damn diploma!”

          Don’t ask me how I honor we
          Bent’s my knee, I say for free;
          Ask the man who swigs with flare, it’s
          Always July Fourth somewhere

          For Worldly is our land forever:
          Worldly blood we feed the thresher
          Worldly trade in fuel and fire
          Worldly reason, worldly liar

But at home we flag our freedom
Bend our knees and say “Te Deum”
Roll some coal and die with honors
Cheer our gods and our embalmers

Even while our pockets’ poorer
Point some fingers, spread some horror
Pardon if I sound so bleak, but
Solace, then, we’re not unique

          Worldly is our land forever:
          Worldly blood we feed the thresher
          Worldly trade in fuel and fire
          Worldly reason, worldly liar

          Don’t ask me how I honor we
          Bent’s my knee, I say for free;
          Ask the man who swigs with flare, it’s
          Always July Fourth somewhere
