Oscar-winning actress JODIE FOSTER spoke at the University of Pennsylvania's commencement ceremony on Monday (15MAY06), ending her address with a surprise quote from rapper Eminem's hit LOSE YOURSELF - the end chorus. The actress, who graduated from Ivy League rival Yale University in 1985, received an honorary doctor of arts degree. The SILENCE OF THE LAMBS star earned laughs from the graduates by taking pictures of them from the podium and recalled her own college days at Yale. The speech struck a serious note when Foster said the US and the world are worse off than they were four years ago and challenged graduates to become active in turning things around. AIMEE MASTERS, who received a bachelor's degree in sociology and women's studies during the ceremony, said Foster was "really inspiring." She says, "Everyone around me was really happy with what she said." Masters added that the Eminem quote "was surprising, but I liked it."
