I don't have too many of them, but I like to dabble here and there in my RLM's (Really Long Meetings) at work.
This one is one I wrote to provide some backstory about Barnabas the Barmy (the wizard on the mural across from the Room of Requirement who tried to teach Trolls ballet).
Enjoy:
Come now dear children and I shall tell,
a true, sad story I know so well
'tis a tale of a man, so creative and brave
a dying art he strove to save
He had an idea, many thought him mad
but he knew if it worked, more would be glad
The idea he had was certainly not droll
He was determined to teach ballet to a troll!
Though clumsy and large and mean they may be
Ol' Barnabas just laughed and said "leave 'em to me!"
And off to the mountains and caves he did go
and gathered up ev'ry one, no matter how slow
He charmed soft music to play from a rock
and slowly stepped back and carefully took stock.
"Okay now lads" he yelled full of glee
"Pay close attention and imitate me."
He threw up his hands and twisted and spun.
Then stopped, face flushed, and cried "Doesn't it look fun?"
"Now come on you lot, let's see a smile,
arms over your head-now spin all the while!"
The trolls raised their arms and twirled clumsily around
Barnabas watched proudly, then suddenly frowned
As he watched the large creatures all flailing about
he thought very carefully, then figured it out.
"I know what you need!" he yelled, startling a few
And with a flick of his wand, magic happened on cue
and ev'ry troll looked down, surprised to see himself
in a short
pink
frilly
tutu
The trolls glared at each other, grunted and shook
Barnabas was pleased, a smile his face overtook
One of the trolls looked around, a large looking fellow
he quickly spied a club and let out a bellow
lifting it high, he twirled and he spun
right over to Barnabas, who clapped from such fun
then stopped quite suddenly-his eyes filled with dread
as the troll lowered his club, right down on his head!
And thus ends the tale of Barnabas the Mad
who is known for the silliest idea ever to be had
And the moral of this tale that you should take home
Is to leave trolls of all types, very much alone.
Ah well, I never claimed to write good poetry.
