It appears that I spoke too harshly, too soon. There's some sort of rule about altering titles, and I don't think it includes an exemption for stealthy jokes. No, MY use of 'stealthy' is not intended as a pun.
In the future, I won't do it then....For great justice. As I said before, I didn't take offence, so there's no problem. I was more surprised than anything. And your point is very well taken. No more editing titles from now on.
