The two that I've never forgotten were as follows:
1. "The subject of today's 'Famous Last Words' segment is Mama Cass, of the Mamas and the Papas." Leary did not say anything, but instead got this bug-eyed look on his face, grabbed his throat, and made a seried of gagging noises (Mama Cass died of some kind of health complications , but for years there was urban legend floating aorund that she choked to death on a chicken bone).
2. "The subject of today's 'Famous Last Words' segment is Billy Martin . . . Hey, you bastard -- gimme the f'ing keys! Don't tell me I'm too drunk to drive."
