madam hooch
a brain-dead fool who can't play quidditch and gets stuck being the ref because no one else wants to look at them
The ref was so dumb, I thought he was a ghost who forgot to haunt the right broom.
Madam Hooch tried to catch the snitch and fell off her broom like a sack of potatoes.
She called a foul because the bludger looked at her wrong.
