Why, oh why

1. Why can't a dish break a hammer? Tell me why, oh why. Because a hammer's got a pretty hard head, Good-bye, good-bye, good-bye. Chorus: Why, oh why, oh why, Tell me why, oh why. Because, because, because, because. Good-bye, good-bye, good-bye. 2. Why can't a bird eat an elephant? Tell me why, oh why. Because an elephant's got a pretty hard skin, Good-bye, good-bye, good-bye. Сhоrus: 3. Now why won't you answer my question? Tell me why, oh why. Because I don't know the answer, Good-bye, good-bye, good-bye. Сhоrus:

why can't a dish break a hammer? - почему тарелка не может сломать молоток?
because a hammer's (has) got a pretty hard head - потому что у молотка довольно крепкая голова,
why won't (will not) you answer my question? - почему ты не отвечаешь на мой вопрос?
because I don't know the answer - потому что я не знаю ответа.
