What is a sample script of an emcee on graduation day?

Parents, family and friends of the graduating class of 2012, welcome. Graduating students, welcome.

Today, you close one era of your life and embark on the next. It is a day to reflect and celebrate. You will soon go off to celebrate with family and friends, but now you celebrate one last time as members of the class of 2012.

And here to present the next speaker is your favorite principal and mine, (name of principal).
