1. Will and Grace (Now on WE tv)
2. Friends (TBS)
3. Boy Meets World (MTV 2)
All of these shows were able to get messages across without being disrespectful, racy, or violent.
They are all still on television and I hope that the younger generations are watching and seeing how shows can be funny, heartfelt, even controversial but in a mature and professional way.
These shows did it right. Watch and learn.
