The little guy fainting is Dante Alighieri, author and protagonist of the 'Divine Comedy'.
In it, particularly during his journey through hell, whenever he sees some scary shit or conveniantly needs to travel from one side of a river to the other without a bridge, he faints (and wakes up on the other side).
Whenever he faints, he uses this expression: 'E caddi come corpo morto cade...' or 'And I fell as a dead body falls'.
That's about it :-)
I'm thinking about looking for some work opportunities in animation shorts like this so I'd really appreciate feedback, good or bad. Let me know what you think in the comment box and make sure YOU survive the zombie rainbow pony war!
