I like this show but in this episode nothing was really accomplished. Rev Run was supposed to talk to the boys about the Facts of Life, but he first brings up Diggy and JoJo's issues with girls in front of some dudes outside of the family. When you do that to your kids, it's more than obvious that later they won't want to open up with you for a talk about sex. And this is precisely what happened.
This is the first episode when we see Russell, (Rev Run's brother) in all of his cursing glory. He is definitely not my favorite person on the show, though I've learned to tolerate him.
Run's idea of 'teaching by example' isn't a bad one in principle, but as we see in other episodes, Run himself still has to learn some stuff about treating his wife. I guess nobody is perfect.
