In this episode Mikey is pretending he is Ozu's son. But Guano was Ozu's son. It was revealed in the Christmas special.
Mitsuki: What's the matter, Mikey?
Lily: Another restaurant ban you for picking your nose with chopsticks?
(Gonard picks up greeting card Mikey dropped)
Gonard:(reading card) Happy Birthday to the world's greatest son. MOG! It's my birthday!?
Gonard: I know how to turn that frown upside down. (Gonard starts doing a stand up comedy routine) How 'bout that Ozu folks? I mean he's so old, I told him to act his age and he died! And his shoes, hiyo!
Lily: There's no way you two taught that bird to fly.
Guano: What are you even doing here?
Lily: (chuckles) mocking you.
Gonard: Don't listen to 'em Reggie, you'll show 'em. You'll show 'em all! (serious tone) especially Mitsuki.
(Talking about the shark)
Mikey: It didn't hurt anyone expect us and Yes Man and the shark that ate Yes Man.
(Scene switches to Yes Man inside the shark)
Yes Man: It's cozy in here!
The title, Like Ozu, Like Son, is a parody of the famous quote "Like father, like son."
