Fudge is a man who Jimmy McGill represented in court for public masturbation.
After Jimmy McGill and his filming crew arrive at the military base, Bauer takes them to the FIFI plane. Bauer begins to ask Fudge about his experience in the war, when he starts coughing. Bauer runs to the base to get water for him. Jimmy and his crew begin filming the commercial while Bauer is away. When he returns, he has a group of soldiers with him, who wish to take a picture with Fudge. ("Fifi")
Fudge appears in the finalized version of Jimmy's commercial for his own law firm. ("Klick")
