Role on the show
Lutz infamously called Liz a cunt in "The C Word". Also in "The C Word", it is stated that he was originally from Alaska, where he hated it, and that his grandmother recently died. His first two initials were mentioned in "The Aftermath", where it was also stated that he has a thyroid problem. In "The Baby Show", Lutz says that he likes to get yelled at during sex. Often, when characters enter the room to make an announcement, they will yell "Shut up, Lutz!" even though he wasn't saying anything at the time. He also mentions that he attended Oberlin College and that after his junior year there he roadtripped to SXSW.
In "MILF Island" he claims that he has had a makeover and even shops at American Eagle Outfitters, but Frank tells him that he is still the dirtbag he's always been. In Sandwich Day it is revealed that he has had surgery for not one but two undescended testicles. In "Mama Mia" he claims to know karate, but this proves to be questionable when he is beaten easily by Donald, the man posing as Tracy's illegitimate son, after some incredibly questionable karate of his own.
