In September,  Obama issued a challenge to the GWU class of 2010 – promising that if students performed 100,000 hours of community service during the school year, she would speak at their commencement ceremony.

Students at the university a few blocks from the White House more than met the challenge and Obama kept her word.

The Washington Post said that “by the time the first lady took the stage, the count was up to 163,980 hours of service.”

“I will say that if I had known that you’d complete more than 3,300 hours on the first day of the challenge I’d probably have picked a higher number,” Obama said during the ceremony on the National Mall.
