Kathleen Turner
Kathleen Turner was ahead of her time playing Chandler's transgender father. Whether you remember this character as Charles Bing or as Helena Handbasket, you definitely remember the stress Chandler had because of it. Ah the 1990s, what a wild and totally different time.
Elliott Gould
No one can appease the Geller family, especially when Elliott Gould is playing father Jack Geller. He has a knack for making an awkward situation a million times worse by being incredibly inappropriate. With Ross and Monica competing for their approval, chaos and hilarity always ensue.
