Duane Moffat is Kimmy Gibbler's boyfriend in season eight of Full House (portrayed by Scott Menville). He does not talk much to Kimmy, or anyone else for that matter. His recurring phrase (to the point of annoyance) is "Whatever". He does not care about many things, except Shakespeare, which he quotes soulfully. He is very easygoing. He even agrees to marry Kimmy. They almost get married at the Create-Your-Own-Wedding Chapel.
In Fuller House, Duane makes an appearance in the episode "DJ and Kimmy's High School Reunion", where he uses his skills as a motivational speaker to help Kimmy overcome all of her embarrassments from that evening.
Kimmy: Duane here is a Shakespeare freak! Aren't you, my little Hamlet-and-Cheese?
D.J.: Duane, you're into Shakespeare?
Duane: Shall I compare thee to a Summer's day? Thou art more lovely and more temperate. Rough winds do shake the darling buds of May, and Summer's lease hath all too short a date.
D.J: Wow, Duane, I had no idea you had such a sensitive soul.
- Duane's last name was never revealed on Full House. However, in the Fuller House episode "DJ and Kimmy's High School Reunion", he's wearing a name tag giving his full name as "Duane Moffat".
