Per Wikipedia,
"Blame Canada" is a song from the film South Park: Bigger, Longer & Uncut (by Trey Parker & Marc Shaiman). In the song, the fictional parents of South Park, led by Sheila Broflovski, decide to blame Canada for the trouble their children have been getting into since watching the Canadian-made fictional movie "Terrance and Phillip: Asses of Fire," and imitating what they saw and heard in the movie. The parents refuse to accept that by not preventing their children from watching Terrance and Phillip in the first place, they are themselves to blame for their children's misbehavior (on the obvious grounds that they do not want to look like bad parents). Thus the South Park film satirizes scapegoating, and the reactions the creators of South Park expected to receive from the very movie the song was featured in.
Blame Canada is also the title of a book about South Park written by Dr. Toni Johnson-Woods, who is an Australian academic and expert in contemporary popular culture. In it, South Park is examined as a modern popular culture icon and described as carnivalesque within the theoretical framework of Mikhail Bakhtin.
So, jump on the bandwagon, and blame the Canucks along with the rest of us...
