Long before she was on The View, Whoopi Goldberg was an amazing stand-up comedian whose work always made me laugh and THINK. She somehow always had a way of using humor to stop me in my tracks and see things from another perspective. I admire the way she uses humor to make people stop and think, to question the status quo.
In her original Broadway show Whoopi Goldberg: Live on Broadway, she did a piece that really challenges people's perceptions about external appearances. Here is a young man's version of that piece that I found to be very powerful (thanks to my mom for sending it to me!)
If you never had the chance to see Whoopi's stand-up, you can check out one routine here from the revival of her 1985 Broadway show, Back to Broadway (warning: some swear words are used in this routine.)
