haha, three Simpsons references in one night, that's incredible, Andrew. I don't even know a single Simpsons line, and I've been watching that show for years.
It's about to get worse.

Smoove: Throw a couple pebbles at her bedroom window to gently wake her up. Seranade her with a love song using your guitar outside the house. After the song's over, take a ladder and proceed to climb up to her window. If she doesn't let you in, take a rock and smash the window open. After the break and enter and the screaming subsides, you then can ask her to the dance

"Oh, you want a rock fight, eh?"
Go to her house while everyone's out, write "WILL U GO TO THE DANCE WITH ME" in big letters, with petrol, on the grass out the front. Then douse the inside of the house with afformentioned petrol. When they're all asleep, throw a match into the house and then set the lawn on fire... that way, while they're all trapped upstairs in this blazing inferno they'll look out the window and see "WILL U GO TO THE DANCE WITH ME" written on the lawn. It'd be romantic.

"Surely you knew as you were writing your name in 40 foot high letters you would be caught!"
"Maybe it was one of the other Barts..."
"There
are no other Barts!"
imma go to her locker in the mornin, place a tiara on a pillow (royal, prestigious style). on the mornin announcements, ask her "will you go to homecoming with me" afterwards, i'll go to her class, then i'll ask the teacher if she can be excused to go to her locker. she looks at the tiara i say "if you dont win the homecoming queen, you definitely are a winner in my eyes" pull out flower (not rose, apparently that's too cliche) and let her answer. its almost full-proof.
I'm with Colin and the rest, I'm not a huge fan of that idea...but I suppose it depends on her personality. Also depends on your intentions, because to me that sounds like you've got a view towards being more than "just friends".
