摩登原始人 第五季

This popular animated television cartoon featured two Stone Age families, the Flintstones and their neighbors, the Rubbles. Much of the humor was based on its comic portrayals of modern conveniences, reinterpreted using Stone Age 'technology.' Most notably were their cars, complete with absence of floorboards to allow them to be 'foot-powered.'

好像有個類似的卡通有山洞，或者就是這個卡通的某一集。天啊居然是1960-1966的卡通，不懂怎麼1990年代電視會重播！
