Finn mac Cool was a construction genius. Rumors swirl that he built the Giant's Causeway in Northern Ireland as a bridge between Ireland and Scotland so he could stroll right across. (Source.)

Finn's lovely locks definitely earned him his name: "Finn" means "blond" in Gaelic. (Source.)

Finn's got cousins across the water. A lot of stories revolving around him parallel those of Britain's macho man, King Arthur. (Source.)

Texas knows how to get its Irish on. That state has a Gaelic football team named after Finn.
