When the semi-wild, semi-unscripted MuchMusic Video Awards consume Toronto's Queen Street West on Sunday, June 16 you can be certain something memorable will happen.

Although it's nominally an "awards" show, the event is mostly an excuse to shut down all the city streets around the Much building and then have international superstars perform in a giant televised block party.

This year Taylor Swift, Armin van Buuren, Avril Lavigne, Psy and Demi Lovato will be among the acts appearing and/or performing and we're certain at least one of them will do something worth talking about for years. (Who wants to bet Avril moons us again?)

We know this from experience because we've been there and seen many of the best and worst moments from past years. Here are a handful of them. Oh, and let us know what we missed in the comments.
