"Get in the hole!!" Golf Crowds are Out of Control

There is an epidemic going around the golf world.  Spectators have this idiotic need to yell the most ridiculous things after a player hits his/her shot.  There has always been that moron that shows up screams "get in the hole" after a player tees for on a par 4 or 5.  They think they're being funny, but nobody it laughing.  The PGA needs to being to make it a part of the spectator rules that some loud mouthed idiot will get kicked out for screaming "mashed potatoes" right after a player makes contact with the ball.  This game used to be a game of high class individuals, and while times have changed and seemingly everyone can play golf, the fan base seems to get rowdier and rowdier.  Augusta has it right, during the Masters there is a team of security guards who follow the players from hole to hole.  These guards have the authority to remove anybody from the grounds if they decide to scream yaba daba doo after someone hits their shot.  These patrons don;t just get removed for the day or week, it is a lifetime ban.  If only every golf course and tournament director followed with the Masters.  It seems that fans are getting louder and louder, often distracting golfers who are on holes near them.  At what point does the PGA do something?  When do they step in and say enough is enough?
