According to comedian Conan C. O'Brien '85, the Class of 2000 better take full advantage of any social functions tonight, because they sure will get their rest tomorrow during Amartya K. Sen's Commencement Address.

"My goal is to be half as funny...as moral philosopher and welfare economist Amartya Sen, " said O'Brien in his Class Day address yesterday. "Better bring a calculator. It will be a nerdfest."

O'Brien, the host of "Late Night" and former two-term president of the Harvard Lampoon, a semi-secret Sorrento Square social organization that used to occasionally publish a so-called humor magazine, delivered a comedic 20-minute address at the approximately two-hour long program.

The afternoon also included a moving Harvard Oration by Brooke M. Ellison '00, a second Harvard Oration by Jason R. Stevenson '00 , the humorous Ivy Oration by Jacob F. Lentz '00 and opening remarks by First Class Marshal Justin M. Krebs '00.

O'Brien reminisced about his time at Harvard before recounting his rise to fame.

"I was very honored to be invited as Class Day speaker. The last time I was invited to come to Harvard it cost me $110,000," O'Brien joked.

The opening half of his address focused on the Harvard experience.

"I had the ugliest picture in the freshman facebook," O'Brien said. "I thought it was for Harvard's private records...Then, they put my picture next to [a woman] who deferred admission to star in Dynasty."
