In the 1900s Argentina had a tax on unmarried men that included an exemption for single men who had proposed to a woman for marriage but were rejected. Women then started proposals rejection businesses where they would charge to turn down proposals from bachelors seeking to evade the tax.
In 1977, Argentina flew a pregnant woman to their military base in Antarctica so she could have first baby to ever be born on the continent. In doing so, the Argentine government believed this would give them an undisputable claim on the land, but the claim is not recognized internationally.
Argentina sent a pregnant woman to Antarctica, had her give birth there, and used the baby to reinforce its territorial claims.
