"I truly liked and admired Bruce. I worked with him some and he helped me in my foot movement and back fist. Bruce probable weighed 135 pounds at most, but he could hit like a mule. I know, because he knocked me under Sharon Tate’s barstool at Columbia Pictures in 1968. Bruce never confronted any big men to my knowledge. There are stories out there, but none I personally know of. I will say this; I would have picked Bruce in any street situation. He had the knowledge and the attitude to carry him through anything."
