LOS ANGELES (AP) ? He's been a race-car driver, a Santa's elf, a TV anchorman and now that he leaves the University of Southern California with an honorary doctorate in hand, Will Ferrell told fellow graduates Friday that he's ready to deliver a baby on an airliner. "Hopefully it will be on United Airlines, from which I will be immediately subdued and dragged off the aircraft," Ferrell added to roars of laughter as he delivered the commencement address to USC's 134th graduating class.
