简介:别沮丧,玩具从天降一场比赛中,你在现场扯着嗓子为其呐喊助威的那支球队最终输了,恐怕你会相当不高兴!不过此时要是有2万个泰迪熊玩具从天而降,来慰藉你受伤的小心灵,你会不会破涕为笑呢?别以为我在异想天开,这"喜从天降"的事就发生在不久前的一场冰球比赛后。加拿大冰球联赛中,主场作战的CalgaryHitmen队虽然没有击败客场来挑战的MedicineHatTigers队,但为了不让主场上万名球迷失望,CalgaryHitmen队为球迷们精心准备了25303只泰迪熊!当比赛结束的那一霎那,无数个泰迪熊从场馆的顶棚上飘落而下,本已泄气的球迷们顿时欣喜若狂,平均每人2只的安慰奖,相信足以弥补球队那差强人意的赛场表现了。
