I, IWM, present to my lovely readers:

50 WAYS TO ANNOY SNAPE

I metamorphed into Lily Evans.

Snape looked at me and color drained from his face.

"L-l-lily?"

"Yes Severus", I said in a ghosty voice.

"I've come to HAUNT YOU!"

He turned tail and fled.

I followed him.

"SNAPE!"

"Miss Santiago, why are chasing Professor Snape?", Dumbledore asked, caught waiting as I ran after Snape.

"Your orders, Professor", I said, wide eyed.

"Very well", he chuckled.

"ALICE!", bet you can guess who that is.
