Alliterated alphabet poem, this variation is written with almost every word within the line beginning with the same letter of the alphabet.
Tail Wagging by Judi Van Gorder
Telling two trollops to take time to testify.
Unrelenting umpires usually understand
Vesting vapid vulgarities
Without woefully worrying wanton women.
My thanks to Judi Van Gorder for years of work on this fine PMO resource.
