My great grandparents, great, great grandparents, were not Native Americans.

So this summer, while you're building sandcastles at the beach, you can thank your heroic great, great, great grandparents for skipping school so much, they literally had to give us the whole summer off.

所以，这个夏天当你在海滩上堆沙堡的时候，你可以感谢你英勇的曾曾曾祖父母，因为他们之前不上学，才让我们整个夏天都可以好好休息。
