Robust version and with test specs! 

def name_shuffler name
  name.to_s.strip.split(/\s+/).reverse.join(" ")
end

require "spec"

describe "#name_shuffler" do
  it { expect(name_shuffler "Foo Bar").to eq "Bar Foo"}
  it { expect(name_shuffler "Foo    Bar").to eq "Bar Foo"}
  it { expect(name_shuffler "   Foo Bar").to eq "Bar Foo"}
  it { expect(name_shuffler "Foo Bar   ").to eq "Bar Foo"}
  it { expect(name_shuffler "Foo").to eq "Foo"}
  it { expect(name_shuffler "   Foo").to eq "Foo"}
  it { expect(name_shuffler "Foo   ").to eq "Foo"}
  it { expect(name_shuffler "").to eq ""}
  it { expect(name_shuffler nil).to eq ""}
  it { expect(name_shuffler 777).to eq "777"}
end

output
