Peeves.

So I was joking with a few friends in a Chatterbox on a Xanga account last week, and I suddenly decided I now possess the power to be almost infinitely distracting to certain types of people. I thereby proclaimed that "I am become Peeves, Annoyer of Worlds!"

I like it. I think I might make it my e-mail signature or something.

No props for getting the modern reference. Harry Potter has been everywhere for the last three weeks. However if you get the original literary reference, or the scientific reference from the 1940s, you do get props for that.
