Each one has a job to do in the grating convoy.

There must be ten trillion fleas at barnyards to molest.
Each one has a job to do in the irksome unrest.

There must be ten trillion flies at picnics to incense.
Each one has a job to do in the galling offence.

There must be ten trillion ticks at fauna to be-leech.
Each one has a job to do in the ruthless outreach.

There must be ten trillion worms at thickets to infest.
Each one has a job to do in the nasty contest.

There must be ten trillion mites at mantles to abrade.
Each one has a job to do in the vector crusade.

There must be ten trillion bees at gardens to enrage.
Each one has a job to do in the testy rampage.
