I have heard that the cast of the show is very close to each other, especially Henry Winkler and Ron Howard. Winkler is the godfather of Howard's children. Its good to know that they are close to each other off the set, as their charcters were on T.V. All you mostly seem to hear about is feuds going on between certain cast members of most shows.

Yes they are a very close knit group, I think one of the reasons is because they traveled around the country and world together playing softball games for charity.
