Seamus Levine (pronounced "SHAY'-muss") is a tough fisherman with wood for arms and legs. He is also blind in one eye, and so wears a black eye-patch. He is a blatant parody of fictional salty sea-dogs and pirates.
He once again emerges from the shadows to warn Peter about the dangers of the sea in "The Perfect Castaway", this time about the enormous waves which could destroy his ship.
For some reason he carries around, rolled up in one of his wooden arms, a picture of a diseased prostate, a cat doing pull ups, a map of Middle Earth, and the band Primus in "Stewie Loves Lois", seen when Peter starts having prostate troubles.
He also has a habit of writing somewhat-lame jokes, featuring outdated terminology, and then asking whether they are successful or not, for instance in "Movin' Out (Brian's Song)", when Stewie refers to the cobbler and apothecary.
He has wooden arms and legs, and has even been asked about this wooden body parts in "A Fish out of Water", when he sarcastically snarks, "No, me father was a tree." He later claims he was a wooden puppet carved by James Woods and in a parody of Pinocchio, was wished to life, claiming Woods didn't wish hard enough, only bringing his head to life, in "And Then There Were Fewer". Though, he later states to just have been a regular guy, until he got baked one night with James Woods, who ate his arms and legs.
In "Ocean's Three and a Half" when Seamus is seen naked, his body is entirely wooden while his head is human, bringing into question how he can sustain life.
He gets a ship in a bottle for Christmas in "Road to the North Pole".
In "Tiegs for Two", he attends Quagmire's class on how to pick up women.
In "Cool Hand Peter", Seamus attempts to join in Peter, Joe, Cleveland and Quagmire's road trip only to be rejected by Peter.
In "The Blind Side" he tells a woman in a bar, who also has wooden prosthetics, that his limbs are made of cheap plasterboard and he can't get them wet.
In "The Simpsons Guy", during the courtroom scene, he is seated next to the Sea Captain.
While fishing in "The 2000-Year-Old Virgin", Seamus hauls in a load of laptops, dumped by the likes of people such as Peter to hide porn of various nature.
