It is graduation time in the United States, and universities compete with each other to get good commencement speakers. For my graduation from UC San Diego, they created an all-campus ceremony so that then President Bill Clinton could give a policy speech on diversity in the United States. Probably the most sought after speakers though are comedians. There were a couple good ones this year with Conan O'Brien giving the commencement address at Dartmouth, and Stephen Colbert at Northwestern University.
I would also like to offer my congratulations to the very first class of third graders that I taught, who graduated from high school this week. All the best for your futures.
