There is a certain formality to the graduation ceremony that I believe should be preserved, and students who significantly disrupt it should be escorted out.  There is a time and place for most things, and the pomp and circumstance of the ceremony is so important to a lot of people.  It only takes a few erratically behaving students to ruin that experience for everyone.

Graduation is a time of ceremony and celebration.  Both are needed.  Just as someone might insist on order and quiet at a post-graduation party seems out of place, so does the student who gets out of hand at the formal party of the graduation ceremony.

There are far worse things the schools should be lecturing about than silly antics at high school graduation.  Crazy gestures are a tradition of graduation in their own right.  It's a time of celebrating for the students, not the teachers or strangers in the audience.  The graduates are all in a happy mood and want to share their enthusiasm with each other, who they may not see again for many years or at all, and their families in attendance.  Let them!  It's High School, for crying out loud. Not Harvard!

I would love to see every person who did something crazy or improper at their high school graduation be sent a letter stating that they never should have graduated, their diploma is temporarily revoked, and their position in the workforce is to cease immediately until the situation is resolved.  This country would fall to its knees! Some of the brightest minds today responsible for technological and medical marvels, and most skilled businessmen/women who have kept us afloat in dire times did something crazy at their high school graduation.  Those are the students who aren't afraid to shine, aren't afraid of being noticed and going for the gold in what they believe in and in life.  

I would limit the antics to exclude vulgarities, but beyond that is just absurd.  Withholding a diploma for students doing the wave? Are you kidding me?  Ridiculous!

yes   because it is indiscipline behaviour,cz they drink alcohol ad u mast take action

This is a very interesting question. When I graduated which was is 1993 from highschool, kids would clap, screamed stuff life the student's name out, and other things like "grats". However, I just recently went to a local graduation where the parents were yelling out curse words, throwing stuff at the faculty, and calling them names. One boy yelled out the "f" word to all the administration and it was rather shocking to say the least.
As I sat back and observed this type of behavior, I realized there is a sharp decline in "respect and manners" in today's schools. It appears to be getting worse too. I also noticed that everything they tried to do (even police) had no bearing. I personally would not want my child to graduate in this situation and she won't, but for the parents who can't help this environment, I think its fair to have consequences. After all, these are young women going into the work force. There should be some type of punishment/penalty for extreme misbehavior.
I think the BEST thing to do is have a class on graduation and what it means along with a manners class. But there is really no simple solution other than to not hold the ceremony and mail the degrees (which is an option) and the parents can hold their own local ceremony.

young women and men is what I meant to say above..

Lots of interesting responses.  First of all for many students this is the end of formal education.  Society expects maturity and a degree of how they will behave in the work world.  Second, the next step may be Harvard for some!  Third, families gather to celebrate the completion in most cases of a free public education and the successful completion of course requirements.  A certain degree of decorum for the occasion is expected as respect for faculty and graduates.  Less that that is a sign of immaturity and lack of readiness for the grown up world.
