I just read this on a ND message board.
There is a long and rich history of pranks committed by USC fans against their football opponents, although usually the pranks are between USC and UCLA during the week before their annual game. This prankster culture is very much a part of the USC (and UCLA) football tradition. Maybe this time USC fans channeled their prankster cravings towards Notre Dame and especially towards Manti Te'o, the top USC recruit who was snatched away from USC on signing day by the Irish.
If you Google "USC football prank" you can read countless stories of dramatic USC football pranks over the years, which go back at least as far back as 1941, when USC students stole the UCLA "Victory Bell" right out of the rooting section, loaded it onto a truck, and hid it for over a year. More recently, in 2008, USC coach Pete Carroll was one of the perpetrators of a prank played on his own players during practice. Actor Will Ferrell and a stuntman were also conspirators in on the prank, in which USC football players watched the stuntman fall from a tower adjacent to the field, apparently seriously injuring or killing himself. In reality, the stuntman landed safely behind a fence, out of view of the horrified USC players who watched him fall. After allowing the USC players to suffer for a while, Will Ferrell eventually emerges from behind the fence, dressed in a superhero costume and carrying the stuntman, as if he had heroically caught him and saved his life:

So the USC football tradition includes pranks which fake the deaths of people, in order to cause temporary emotional anguish to the prank's victims. As with most prankster competitions, as the years go by, the severity of the harm caused by the pranks back and forth tends to increase, to the point where immature and probably intoxicated fans exercise extremely poor judgment by taking a prank too far. For USC fans, the target is usually UCLA, but Notre Dame is USC's other big rival.
I don't think it is far-fetched at all to believe that the Manti Te'o hoax was cultivated in this deeply ingrained culture of cruel pranks by USC fans and former players.
So Pete Carroll devised this plan (referencing the Will Ferrell thing, not Te'o), not out of good natured humor, but to put his team under emotional distress... This has to be one of the stupidest thing's I've ever read on the internet, which of course is chock full of stupid things. I know that sometimes we, as CFB fans can get a bit over the top and pretty far from reality, but this takes the cake.
