Ha-huh! Amazing! Three minutes in the kitchen and our son has taught him to talk in complete sentences. Oh, good work, son!
— Marty after hearing SpongeBob talk proper sentences, "I'm with Stupid"

Marty is Patrick's fake father. He appears as the main antagonist of the episode "I'm with Stupid." Marty is married to Janet and comes to Patrick's house for Annual Starfish Day.


He is a reddish-pink starfish who has bushy eyebrows and wears a gray tank top and blue shorts. He is a darker shade of pink than most other starfish in the series.

Role in episode

SpongeBob pretends to be dumb for Patrick's fake parents. He is not quite smart himself, though.

Even though SpongeBob reveals the truth about Patrick, Marty and Janet still don't believe Patrick is dumb and start laughing at SpongeBob, who runs out of the house in a fury. When Janet and Marty reveal their real names, Patrick gasps and demands to know who they are.

Before Patrick can do anything, Squidward arrives with another starfish couple, who reveal themselves to be Patrick's real parents. Janet and Marty realize they don't have a son and leave.


  • "He's short-circuiting! You must have taught him too much!" —"I'm with Stupid"
  • "Wow, son! You put the drinks in something this time! Ah, son, you must've been working all night to put these together for us." —"I'm with Stupid"


  • Like Janet, who resembles Marge Simpson, Marty resembles Homer Simpson from The Simpsons.
  • Even though he makes fun of SpongeBob's stupidity, in the end, it's revealed that he doesn't even know that Patrick is not his son. Since this is his and Janet's only appearance, it is never revealed if they even have any kids at all, or if they're even related to Patrick.
