After writing this, I realized how little I know about funk, but anyway...
Harry and Voldemort are at their final blow in the 7th book. Hott dog, Harry's 17 years old! wow! In mid-duel, Harry stops and starts his funky song
"You'll never defeat me, Potter!" Voldemort shrieked as Harry dodged a curse.
"This battle is only half way through, Tom!" Harry shouted back, then paused.
"Which means," Harry said, facing the audience, "it's time for my funky intermission!"
"What are you talking about, Potter!?" Voldemort shouted as back-up dancers with big hair and in tight clothes suddenly appeared to with multi-colored lights bouncing off the ceiling.
Suddenly, a funky beat started and Harry began to sing:
"Today's a funky day
And in my funky way
I'm beating up Tom Riddle
He ain't got a fiddle
Hott dog, I'm seventeen!
Wow! And I'm quite keen
on defeating this unfunky man
In desperate need of a tan!"
The music stopped, the dancers left, the lights disappeared, and Harry faced Voledmort.
"Now that you've seen my funky song, let me show you my funky spells!"
And so the battle continued.
