I believe the former mechanic of a play that gained a new series but stayed inbounds, was the "crank & kill" signal = #2 (twice) followed by # 3. For signal #2, the covering official could assume he was inside of the clock, looking out (counterclockwise) or outside of the clock, looking in in (clockwise).
I believe today's mechanic of above said play is merely killing the clock #3. followed by an internal "twirling" signal -sorta' like twirling ones keys to either a late model Mercedes or an ole' model pickup truck. That way the ECO (we call 'em the timer) will know when to stop the clock.
I believe donning ones uniform in the field's parking lot would only be socially acceptable if one was to officiate a coed nude touch football game. If so, one should keep in mind that the "grope touch" has been determined to be a game disqualification.
Hope my beliefs help...hope the Red Sox will find some pitchers...
