Which Bill Cosby stand up was this?

When I was much younger I had a cette of Bill Cosby's stand up that I loved. I listened to it all of the time. Unfortunately I had a house fire and lost it (among other things). All I can remember from his material was the part where he goes into detail of how the belt his dad would whip him with would tear the flesh, then he also talked about doing some type of soap box derby illegally and the cops were waiting at the bottom of the hill.
