PHILADELPHIA (AP) -- There was no missing Bill Cosby at a memorial for businessman and philanthropist Lewis Katz.
Among a sea of dark suits, Cosby sported red Temple University sweatpants and a school T-shirt.
The 72-year-old Katz died Saturday in a plane crash. He was Cosby's classmate at Temple. The Philadelphia school hosted ex-President Bill Clinton and other dignitaries for Wednesday's remembrance.
At one point during the memorial, Cosby nearly fell off the edge of the stage, later explaining he couldn't find the stairs.
He also joked about having to go to the bathroom during the many long tributes, but he turned serious when he spoke of Katz's legacy. He told mourners to keep up the schools and other projects his friend funded.
Cosby said: "You don't have to have big money. All you have to have is yourself."
