Search: brice all my children
Why: When Joey can't find a good job after "DOOL," Gunther says he used to be Brice on "All My Children."
Answer: Not onscreen! Sometime in 2002 (?), a fellow played the voice of a character named Brice Dickson. (There wasn't a Bryce, either, in case you thought maybe I don't know how to spell stupid names that no one should have.)
The IMDb pages for decades-long soap operas are just appalling. Someone clean them up plz, thx.
The More You Know: James Michael Tyler, originally a nameless extra, was cast as Gunther because he was the only extra who knew how to operate an espresso machine, having worked in several coffee shops before getting into acting. This led to a 10-year career with appearances in 131 of Friends' 238 episodes; he is the show's most-frequently-appearing guest star.
P.S. I made this for you guys at work: The Best Friends Characters. Go vote!
