I couldn't add anything to what has already been said about the 4/20-part, but I've been going in the last week and thought about how T-funk's air over the china banks shouldn't be discussed as a trick of the year, but as one of the greatest tricks of the last decade (just to set a time frame).
What other tricks stand out to you, when you think of the last decade?
Oski's alley oop to nosebluntslide is a trick I think about a lot.
