Dayananda Dasa : After the program we went to a separate room, the brahmachari room, and had a puppet show about Prahlad. Vishnujana had made the puppets. Behind the puppets' screen, Silavati was Prahlad's mother, while Vishnujana and one or two other devotees took other roles. At one point Hiranyakashipu was about to give Prahlad some poisoned food, and there was a plate of sweets on the puppet stage. Prahlad was offering these sweets to his spiritual master, when someone told one of the brahmacharis to bring the plate of sweets to Prabhupada. When Prabhupada received these sweets he said, "Oh, you're trying to poison me?" It was so funny. Prabhupada made this joke, and everybody got a kick out of it.
