The offspring of the “Soixante Re-Tards”.
I did hate learning French numbers higher than 50, because they made no sense. The number 70 is “soixante-dix”, or “sixty-ten” rather than “septante”. Even worse, 80 is “quatre-vingt” (four-twenties) instead of “huitante” and 90 is “quatre-vingt dix” (four-twenty-ten) instead of “neufante”.
