最初的《毁灭战士》拥有一个带有静态墙壁的引擎，但却不能移动;结果，所有的门都是垂直打开的;任何东西都不可能水平移动。当源代码发布后，我在查看代码时，在处理门的源文件中看到了这个，在一大块注释掉的代码的开头:

// UNUSED
// Separate into p_slidoor.c?

#if 0           // ABANDONED TO THE MISTS OF TIME!!!
//
// EV_SlidingDoor : slide a door horizontally
// (animate midtexture, then set noblocking line)
//

我们的DBA在第三方编写的3000行存储过程中发现了这一点。

/* IF DOLPHINS ARE SO SMART, HOW COME THEY LIVE IN IGLOOS? */

try {

}
catch (SQLException ex) {
    // Basically, without saying too much, you're screwed. Royally and totally.
}
catch(Exception ex)
{
    //If you thought you were screwed before, boy have I news for you!!!
}

/*
* TODO: Remove this function

function remove($customer_id)
    {
        $this->Customer->remove($id);
    }

*/

/**
 * Not even your mum thinks you're special if you call this method
 */    
onlyYourMumThinksYoureSpecialIfYouCallThisMethod() {...}

// TODO: Drive an ashen stake through the foul heart of this function.

这是一个糟糕的函数。直到今天我还在做噩梦。
