Why Snape? I rather like him. Why not Dumbledore? He needs to learn some lessons on how to manage people properly. *grin* This was a good story, btw. ^_^

Very imaginative and clever.

Trust Gred and Forge to leave such magical memories that dear Dolores will find it impossible to forget them.

My contribution:

Snarky Seat: I placed a charm on Umbridge herself that would activate anywhere she sat down, causing her chair to keep up a snarky commentary to her every word and action. I'm particularly proud of the modification that caused Umbridge to hear mewing kittens in place of not only the snarky commentary but the resultant snickers and giggles as well. Score! 

 

You are one strange and unusual child.  I do not claim you.  Good premise and execution of all of those wonderful idea's that Fred and George had.
