guys -- very original -- to put down a towel or blanket or t-shirt or something underneath their bum anytime they sit down. they walk around every day in the san francisco district. he said his concern is for the public health and sanitation, not appropriateness of public nudity. what is wrong with this picture? >> greg: this is an injustice against nude men everywhere. why should they fight with the burden of a towel? they should travel the street of castro district naked as the day they were born. i'm not going further. >> bob: you dog people don't make your dogs put it down. you walk around naked. >> andrea: now we're dogs? >> greg: man has no limits. >> bob: anybody that is around me who is nude i expect them to be sanitary.
