First off, I never really watched that much "Friends", but I don\'t see too many blacks hanging out with the cast of friends.
Chanler would be affraid, Ross would get his ass beat for saying something stupid, Monica and Rachel would have babies from the same black friend, so all you would have left would be Fibi and Joey, who would probably end up banging and having little stupid psychic babies.
that would be the end of "friends"
