>Eurasia.

Yes, I'm on board with this - how a jumped up little peninisula sticking off the butt-end of Asia gets to call itself a continent escapes me. I did read somewhere that, at least before the Suez canal was formed, Euafrasia was also a valid alternative.

As for Central America, I once saw a documentary that looked into its origins as an island that drifted into place between the two separate continents of Nth and Sth America. If this is true, then the Americas certainly have a valid claim to being continents, unlike Europe.
