Where Theres A Will Theres A Way Part 2 is a great episode that contains one of the best and funniest moments throught the whole series.
Will and Carlton are moving into thier own appartment. After getting in trouble because Jazz threw a wild party they are forced back to move back home. When they get home Trevor was going to propose to hilary in a special way.
The special way he did it was funny. I would describe it better but I don't want to get rid of the surprise.
This episode is avalible on The Fresh Prince Season 4 DVD. This is one episode that you shouldn't miss.
