I wrote this quite a while ago, and then forgot all about it... The ending means that I used to to know a teacher very similar to Umbridge. She had even been appointed by the Department of Education! Enjoy!
Umbridge
Umbridge could be a frog,
who lives in a bog.
But she's more of a toad,
left by the hot, dry road.
She likes the sight of blood,
she probably thinks she's god.
Acts sugar sweet,
but deserves to be beat.
You may think you'll never meet a woman like her,
but some of us know better.
Two women, so ugly and bad;
they're so alike it's really quite sad.
