CGI stands for the Clinton Global Initiative. President Clinton established this in '05 to gather world leaders to create and implement innovative solutions to our world's most pressing challenges. U2's lead singer, Bono, has been an outspoken activist for accomplishing many of these goals. He also has a good sense of humor.

The Clinton Global Initiative website tells us:

The CGI Annual Meeting is held each September in New York City. CGI also convenes CGI America, a meeting devoted to economic recovery and job creation in the United States, and CGI University (CGI U), which hosts an annual meeting for undergraduate and graduate students who are developing commitments in their communities and around the world.

It's good see to see our leaders getting together with our pop culture leaders to solve big problems facing us. It's also good to see them having fun doing it.
