A recent addition to Wiki Superosity regarding Halloween has helped us recall a most interesting fact: the controversial subject of ghost eating has been broached in Superosity prior to 2009. In a 1999 crossover, Bobby consumed a ghostlike computer virus from an alternate dimension. Given this history of feasting on ethereal beings, it appears that Bobby's objection to Alan and Hedrick's plans may have stemmed from jealousy of his own record.
Later on, he may have also been jealous that he had to suffer indigestion while Alan got to become a homage to one of Arnold Schwarzenegger's greatest comedies. I refer of course to Kindergarten Cop- that bulge in his belly is clearly not a tumour.
