On June 11, 2007, WWE aired a segment at the end of RAW that featured McMahon (in character) entering a limousine moments before it exploded. The show went off-air shortly after, and WWE.com reported the angle as though it were a legitimate occurrence, proclaiming that McMahon was "presumed dead."[5] Although this was the fate of the fictional Vince McMahon character, no harm came to the actual person (that is, his death was part of a storyline).[6][7]
