 CHAR: As he makes a list of the friends who have died during his  cryofreeze, Austin repeats the urban legend that Cass Elliot died  chocking on a ham sandwich; she died of a heart attack. While true  that Momma Cass died of a heart attack, it was a widely held belief  for decades after her death, that she did, in fact, die from choking  on a Ham Sandwich. From Austins perspective, it is likely that he  still believed this version of events.
