WMG: The World/Inferno Friendship Society
Jack Terricloth never lies; he's a reality-hopper.
All the inconsistencies in Jack's stage banter and interview answers are simply the result of a bizarre situation that causes him to awake at random in one of two (or more) parallel universes. In the other(s), everything he's apparently made up has actually taken place; for instance, in one universe the band recorded a punk version of "A Prairie Home Companion" instead of "The Anarchy and the Ecstasy." His repetition of these facts regardless of which universe he's in at the time is either an attempt to merge all the realities into one, or because he just doesn't care.
