Rhyme And Pun-ishment

Why were two flarf poets robbing a bank?
Where did they acquire the Uzis? And, could
they concentrate long enough to pull the trigger?
They handed the pretty cashier the note. To the
cashier who had never heard of flarf, it looked like
a harry k stammer poem. But the flarfists got
their money, they angrily threw the dye marker
at the old Mexican security guard who’d probably
fled Mexico during the revolution. They got into
their getaway car, a Smartcar, they barely fit
in it with their bags of stolen money. Suddenly
two cop cars were on their tail. One of the poets
pointed his Uzi out the window and took out
both patrol cars with one bullet. A police helicopter
appeared overhead. They shot the flying copper
out of the sky. Then they vanished into an
abandoned warehouse. They were never caught.
Who says rhyme does not pay?
