Though I have been told it is the most epic of all. To quote HD "more epic than the Bourne Trilogy." I was flattered.
(Here is a reference if you don't know what BST is)
(Also, this is what I mean by anthrax)
So HD is sitting in some kinda history class with MC sitting close. A student walks in with a Little Caesars Pizza in her hand, and delivers it to HD. Everyone is staring. HD thinks "what the heck? why am I getting a pizza? who sent this to me?" He opens the lid of the box to find a pile of snow (aka anthrax) with a note that reads: "You thought this was a pizza, didn't you?" MC is impressed.
This is probably the best anthrax assassination I have ever pulled off. All I had to do was go to the main office and ask them to deliver a pizza to a student. It was awesome.
