Expecto Patronum

Hey, Harry, I hear you got a problem
Dementors got you down in the doldrums
I'll help you, that I'll teach you a charm
That'll have those hooded jerks running back to their moms
I admit it's not that easy to use
But I show you how to do it, you got nothing to lose
Just follow these instructions of mine
Listen to me and you'll get it in no time!
Think of something happy, think of something happy
It could be complicated or it could be short-snappy
Hey, Harry, maybe think if mom and daddy
Or anything you'd like as long as it's so happy-happy
Alright, are you thinking of something happy?
(Yeah!)
Make sure it's really happy...
OK, the next part is a phrase, consisting of two words
And I'll spell it out for ya!
It starts with an E, stands for "Evil, go away!"
Then an X and a P for puppies, they fight when they play
Then an E and a C and a T and an O for "Oh my, this is easy!"
Then it goes P A T R O N U M - what does that spell?
(Expecto Patronum!)
Woah, woah, woah, you can't go shouting that all willy-nilly like that
You gotta do something first - Remember what it is?
Think of something happy, think of something happy
It could be complicated or it could be short-snappy
Hey, Harry, maybe think if mom and daddy
Or anything you'd like as long as it's so happy-happy
(Expecto Patronum!)
Yay, that was pretty good!
Oh, wait, no... You passed out.
Oh, well, here, have some chocolate, it'll make you feel better.
OK, ready to try again?
(Yeah!!)
Think of something happy, think of something happy
It could be complicated or it could be short-snappy
Hey, Harry, maybe think if mum and daddy
Or anything you'd like as long as it's so happy-happy
(Expecto Patronum!!)
Geez Louise, Harry! Geez Louise!
What an awesome stag!
(Thanks!)
