Sing to the tune of "a whole new world" from aladin. Ron sings Jasmine's part. harry sings aladins.

The Magic World.

Harry: I can show you my scar

Look, it is shaped like lightning

I'm so skilled

I played Quidditch when I was in first year

Potions was such a bore

But then the prince came to save me

With him, potions is easy

Oops! I nearly killed Draco

The magic world

Three headed dogs will try to kill you

Just yell sectusempra

Or even lumos!

But not Avada Kedavra

Ron: The Magic world

The same old place I always knew

But when Lavender is near

It's crystal clear

That Hermione is extremely jealous

Harry: Ron, I'm in love with your sister

Ron: Harry, you sly old fox

Harry you have my permission

To snog my sister senseless

Just not in front of the eyes

Of the magic world

Harry: I won't snog while you see

Ron: I really hope that you do not

Harry: Do you mind if I screw her?

Ron: If you do I'll bust

A cap in your ass

I swear to god I'll kill you

Harry: All right, I'll refrain

Ron: Do you promise? Okay then

Harry: Hey Ron! Isn't that Lavender?

Ron: Oh my god! Harry hide me!

Both: She is a frigid bitch

And should be tossed in a ditch

Distract her while I hit her over the head

Harry: The Magic world

Ron: The Magic world

Harry: That's where we'll be

Ron: That's where we'll be

Harry: A Torrid romance with...

Ron: I'm not wearing pants for...

Both: Hermione and Ginny
