The homeless dude can tell the last thing that people eat. He says pig, for instance, if the person had ham or bacon. Cow if the guy had a cheeseburger. When he says human, some folks assumed that the person he "read" killed and ate a human being, when it is far more likely that the tall businessman is gay, and performed oral sex on someone, swallowing their semen. Ergo, he ate 'human' last.
Hope that helps.
