Billy Crystal-700 Sundays
A semi-autobiographical play featuring Billy Crystal playing various characters of people who have influenced his life.
This was discussed at a family outing recently. All the older folks (ages 55-65) love it and think it's the best things they've seen in a long time. I bit my tongue on the topic, but I really wanted to ask if he put on blackface for the show.
They later made fun of people wearing berets. So, I did some digging and was able to find this picture.

I emailed it to them so I could at least get a slight jab in. Hopefully they realize he's a creep and a half.
