If you want to get really nitpicky about it, North America isn’t just one island, either. There’s at least one “lake” (Lake Isa, in Yellowstone; really more of a marshy pond) which sits right smack on the Continental Divide, and drains both to the East and the West. So Lake Isa, together with the river systems it drains into, would divide North America into at least two islands, as would any other lake with the same property.
You should have upped the recursion by standing in an inflatable pool, with a drink in your hand, with an olive in it - with a little pool of drink in the hole in the olive, and something small - say a piece of pimiento floating in it.
