谁给解释下roses are red,violets are blue,you've got a warrant,and we'd love to seeyou
这句话的意义呢。为啥后面紧跟了这句谁说浪漫已经死了。这句话的浪漫体现在哪呢

玫瑰是红色的,紫罗兰是兰色的,你通过了（你得到了许可证）,我们期待你的表现.
这句话怎么这么奇怪?是哪里的?如果可以的话,告诉我一下,
我想知道这句话是出自哪里?上下句你也贴出来吧
Roses are red,violets are blue,sugar is sweet,and so are you.
But the roses are wilting,the violets are dead,the sugar bowl's empty and so is your head.
娇艳的紫罗兰,鲜红的玫瑰,甜蜜的糖,就像你一样美.
但紫罗兰会凋谢,玫瑰会枯黄,糖碗空空如也,和你的脑袋一样.
……这样看浪漫是不是就没有了?
