"Shhhhhhhh please respect the kicker"

Gordon D'Arcy, Rob Kearney, Brian O'Driscoll and Jamie Heaslip scored tries as visiting LEINSTER beat EXETER, 29-20, in a HEINEKEN CUP match we watched on television today.
Leinster's win maintained a faint hope to make the final eight of Europe's RUGBY UNION championship, but the Irish side must now await tomorrow's results before banking their advancement.
The girls and I enjoyed seeing the Exeter video board that requested fans to pipe down whenever a kicker attempted a conversion or penalty. It was quite the opposite scene of, say, an opposition player attempting a free throw in an American basketball game -- when the fans try every conceivable method to distract the player.
Is this another example of rugby being the true "gentleman's game?"
