I saw him years ago in a club in NYC. Some of the best money I ever spent. There was a last minute replacement for one of the opening acts and it was some young ventriloquist that absolutely bombed. Being an insult comic, I braced for the full Gottfried treatment, but Gilbert came out on stage, shook the kid's hand, turned to the audience and merely said: "Sorry folks, for my act, you only get the dummy." and launched straight into his act. Thought it was very cool that he threw the kid a bone.
I've listened to his podcast from time to time, he was a font of knowledge of Hollywood history
