Защо да е глупост?:-)
Ако прочетеш и разгледаш ВНИМАТЕЛНО, ще разбереш - с помощта на Zеro the Hero обясняват на децата какво е нула, двуцифрените числа 10, 20...имат си традиция да броят 10, 20, 30 ден от началото на учебната година и т.н.
Затова е и тази песента за десетия ден...
Не съм им почитател, но Black Sabbath, Cannibal corpse имат песни с такова заглавие...

The Story of Zero the Hero
Prior to keeping track of our days together we hear the story of Zero. He was jealous because all the other numbers 1, 2, 3, etc. had something to show for their number. (I use number cards & cards with stickers to match numbers as I tell the story) Of course Zero's card is empty. However after the number 9 is display; you cannot count any higher and the numbers were sad. So Zero had a great idea!! He grabbed number one's hand and made a new number 10!! All the numbers were so happy they called him, Zero the Hero! Then we can count 11, 12, 13, etc. up to 19 & then Zero had to be a hero again & this time he grabbed number 2's hand, etc.

Zero the Hero visits our boys and girls on the school days ending in zero. We count each day we come to school. Zero visits us on the 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th day and so on until the end of the school year. Zero really gets excited about the 100th day of school as we have a daylong celebration. He will continue to visit our classroom on other zero days. He visits our room delivering special zero treats and we sing his special song. Here's our song we sing for Zero The Hero when he comes...
