Grey Squirrel: America's Revenge

Long ago, a man named Christopher Columbus inhabited a boat for an inappropriate amount of time and crashed into a distant island, whereby he and his tribe proceeded to kill or enslave all the inhabitants.  

Next came the squirrel, who left America for the distant shores of England.  Here, they encountered their own 'red man,' the red squirrel, that is.  There was a struggle.  Swiftly, their evolutionary history enabled them to poison their aboriginal rivals, thereby rendering the indian squirrel extinct, and ensuring American hegemony.  

Revenge through reverse-colonization?  We think so.
