I think the 'underdog' under stress has the advantage of acting in an unexpected manner and so surprising its predator.
It often happens that when a larger predator has killed a prey animal that had a young, the predator is confused as to what to do with the young ones if it doesn't run away.
That "Media URL" thing keeps knobbling the clickability. As far as I remember the "Enter YouTube Link here" box developed a glitch and AbEd said they were unable to fix it.
Other than that, URLs work best when no other ASCII characters directly touch them. A space character at either end may help. I take no chances and always press return before pasting, so they are on a new line, by themselves
