"you're going to embarrass your mother"

The London Riots (so-called, also known as London shopping free for all) have had me thinking about Bill Cosby's "Pound Cake" speech.

I wanted a piece of pound cake just as bad as anybody else. And I looked at it and I had no money. And something called parenting said if get caught with it you're going to embarrass your mother. Not you're going to get your butt kicked. No. You're going to embarrass your mother. You're going to embarrass your family.
