Audio problem: When Tubby is about to win the race, Mikey shouts "Run Tubby run" in Spinelli's voice.
Suggested correction: Not really. It definitely sounds like Spinelli due to how he screams the line, but it's not Spinelli's voice. Something similar happens a moment earlier in the episode, when Mikey screams, "Win, win, win!" His voice gets a bit raspy, similar to Spinelli's raspy voice, but those aren't the same voices. Also, I don't know why they would have Pamela Adlon (Spinelli's voice actor) record that one line for Mikey anyway.
