Strangest Piece of Code

Post the strangest piece of code you or someone else has written! Mine:
  
//before

int a
int b
int e
//SNIPPET


void SlowComputerDown(e)
{
  for(a=0; a<=(computer_speed()*e); a++;)//computer speed

  {                                     //was found in another

    b+=a                                //function

  }
}

  
But still, I''d have to say, the code was still slow without it (it was a 16bit program, that ran slowly...)

You know, no matter how many times I look at this code, I still can''t recall how I arrived at it. Some parts make perfect sense, but others...

  bool CheckMove(int X, int Y, direction Move){	if(Move==LEFT)	{		if(X==1)//Is the left wall in the way?			return false;//Move is illegal		if((Y!=1) && (Y!=((2*level_size)+1)))		{			if((((X-1)%2)==0) && ((Y%2)==0))//Is there a block in the way?				return false;//Move is illegal		}	}	else if(Move==DOWN)	{		if(Y==1)//Is the bottom wall in the way?			return false;//Move is illegal		if((X!=1) && (X!=((2*level_size)+1)))		{			if((((Y-1)%2)==0) && ((X%2)==0))//Is there a block in the way?				return false;//Move is illegal		}	}	else if(Move==RIGHT)	{		if(X==((2*level_size)+1))//Is right wall in the way?			return false;//Move is illegal		if((Y!=1) && (Y!=((2*level_size)+1)))		{			if((((X+1)%2)==0) && ((Y%2)==0))//Is there a block in the way?				return false;//Move is illegal		}	}	else if(Move==UP)	{		if(Y==((2*level_size)+1))//Is top wall in the way?			return false;//Move is illegal		if((X!=1) && (X!=((2*level_size)+1)))		{			if((((Y+1)%2)==0) && ((X%2)==0))//Is there a block in the way?				return false;//Move is illegal		}	}	return true;//Passed all tests, the move is legal}

This thing is called "Duff''s device". Apparently, it''s some awesome optimization from back in the day

This was taken from the C FAQ: http://www.faqs.org/faqs/C-faq/faq/

  register n = (count + 7) / 8;switch (count % 8){case 0:    do {	*to = *from++;case 7:		*to = *from++;case 6:		*to = *from++;case 5:		*to = *from++;case 4:		*to = *from++;case 3:		*to = *from++;case 2:		*to = *from++;case 1:		*to = *from++;	      } while (--n > 0);}  
Oh dear! I am rather embarrased by this ...
    for(i=0;i<NumObjects;i++){	// if the object can move	if(!obj[i].isstatic)	{				// if moving, make previous location empty		if(obj[i].ismoving)				mapObj[obj[i].srcX][obj[i].srcY]=-1;				// get current location		obj[i].srcX=obj[i].destX;		obj[i].srcY=obj[i].destY;				// decide whether or not to move		obj[i].ismoving=rand()%2;				// if we are moving		if(obj[i].ismoving)		{			// get a direction...			obj[i].direction=(rand()%4+1)*2;						// and a destination based on the direction			switch(obj[i].direction)			{				case 2:					obj[i].destX=obj[i].srcX;					obj[i].destY=obj[i].srcY+1;					break;				case 4:					obj[i].destX=obj[i].srcX-1;					obj[i].destY=obj[i].srcY;					break;				case 6:					obj[i].destX=obj[i].srcX+1;					obj[i].destY=obj[i].srcY;					break;				case 8:					obj[i].destX=obj[i].srcX;					obj[i].destY=obj[i].srcY-1;					break;			}						// if there is an object in our path, don't move			if(mapObj[obj[i].destX][obj[i].destY] != -1)				obj[i].ismoving=0;						t=map[obj[i].destX][obj[i].destY];						// if there is an impassable tile in our path, don't move			if(t!= 1 && t != 15 && t != 19 && t!=21)				obj[i].ismoving=0;						// if the player is in our path, dont' move			if(obj[i].destX==pmx && obj[i].destY==pmy)				obj[i].ismoving=0;		}		// if we aren't moving...don't move		if(!obj[i].ismoving)		{			obj[i].destX=obj[i].srcX;			obj[i].destY=obj[i].srcY;			mapObj[obj[i].srcX][obj[i].srcY]=i;		}		else	// make our destination occupied 		{			mapObj[obj[i].srcX][obj[i].srcY]=i;			mapObj[obj[i].destX][obj[i].destY]=i;		}			}}
