我所见过的最好的评论是

/* 
  There is no accounting for pointers 
*/

 // WARNING!!!
 // Very perversive code ahead!

... about a 20 lines of "very perversive" code ...

// Now you can call your grandmother back. ;)

// nobody read comments!

一些来自Linux内核的代码:

/* Sun, you just can't beat me, you just can't.  Stop trying,
* give up.  I'm serious, I am going to kick the living shit
* out of you, game over, lights out.
*/

-

/* 2,191 lines of complete and utter shit coming up... */

-

#if 0 /* XXX No fucking way dude... */

我没有亲身经历过这种情况，但这是一个很好的故事(详见我的评论中的解释):

#define MSGTAG_B33R     0x723 /* RIPLVB */

在一个名为“Bar”的类中(这是一个不具有描述性名称的UI控件)，类头文件:

/// <summary>I pity the "foo".</summary>

Remove()方法:

/// <summary>A "foo" and his money are soon parted.</summary>

更糟糕的是，业务合作伙伴从生成的文档中指出了这一点。更糟糕的是，这些可能是我们从那家伙那里得到的最接近有用文件的东西。
