11. Steal his Death Eater robes and mask. Corner him and sing songs from The Phantom of the Opera.

Harry was silently laughing at himself as he put on snape's death eater robes and mask and crept to the great hall where Snape was currently eating dinner. He had asked Ginny to be christine and she happily agreed.

Ginny walks over to snape and beings to sing:

In sleep he sang to me,

In dreams he came.

That voice which calls to me,

And speaks my name.

And do I dream again?

For now I find,

The Phantom of the Opera is there,

Inside my mind.

nobody noticed Harry take off the invisibility cloak and stuff it in his robe pocket he then walked over to snape and began to sing:

Sing once again with me,

Our strange duet.

My power over you,

Grows stronger yet.

And though you turn from me,

To glance behind.

The Phantom of the Opera is there,

Inside your mind.

Dumbledore watched with an amused experission while the purebloods either looked confused or astonished and the muggleborns and half bloods who had heard of the phantom of the opera began to clap. "why are you wearing my robes? Who are you?" Snape asked looking confused and angry.

12. In a deep voice, say, "Severus, I am your father"

"Serverus, I am your father" Harry said in a deep voice he then pulled off the mask and bowed to the students before running away from a red faced snape.

13. Create the very first Severus Snape barbie doll. Sell them to everyone at hogwarts.

"Would you like to buy a Serverus Snape barbie doll? Well you can only 3 gallons" Harry said after casting a spell to make his voice louder he was holding the doll he made and had sold quite a lot already.

Snape was walking back to his office from the great hall when he heard potter's voice he walked round the corner to see a rather large crowd around potter he was holding so sort of doll wait it looked like him "POTTER!" He yelled as he ran at Harry.

They sat in the hospital wing Snape had Cornered Harry at the top of a staircase with was changing and Harry lost his balance and pulled Snape with him.

"Princess Cuddles McFluffigan why did you push me?" Harry said to snape smirking "who are you talking to potter?" Snape said scowling. "you" Harry said showing him the leagal form which said:

Severus Snape's name has legally been changed to Princess Cuddles McFluffigan.

"Potter..." Snape said face going red before he tackled Harry and tried to strangle him "You can't legally strangle a student" Harry said grinning while Snape growled and walked out of the hospital wing.

15. Tie him to a chair and make him watch Barney.

Harry tied Snape to his teachers chair and conjured wheels on each leg of the chairs four legs he wheeled a stuggling snape to a t.v screen and turned barney on.

He came back 5 hours later "I love you. You love me..." Snape sang with a smile on his face Harry let out a girlish scream and ran from Snape who was trying to give him a hug.
