This is a completely amazing song. The first time I heard it was on her website, and after that, I bought the CD the next day and I loved it!
Even though, this is my 2nd favorite Avril's song (the 1st one is Nobody's Home, of course), I didn't like very much that she started the concerts from her "Bonez Tour" with this song...here in Southamerica, in Chile, Argentina, Brazil, and also Mexico, and I don't know where else, she started with this song, and the show beginning was kinda the same she used in her 2003 concerts...
Whatever, this song is really really cool and the video is...not very good, though, but very entertaining.
Great song, and most important, great album!
