Nothing wrong with moving them around the pen either, as long as they think you're gonna kill them if you catch them, and wish you had after you've run the daylights out of them.
If I don't have anything else available, and the offense is severe enough, I usually try to get in a well placed kick before they get out of range. It usually just ends up hurting my foot, but it helps my pride anyways. ;o)
Hey Frog, how did your ride go this weekend...any bucking?
