In Adam West's cameo appearance, he makes two references from his acting career: He first makes three nods to his iconic role from the 1966 Batman TV show ("My car is stuck in a cave. Its a long story.", "...I'm not very fond of clowns", & "Back in the day I would have kapow right in the face."). And then he makes a nod to his role from Family Guy ("As mayor of this fair city...").
Noah Gray-Cabey and Leonard Roberts reprise their roles as Miach Saunders and D.L. Hawkins respectively from their TV show Heroes for a cameo appearance when they are picking up a pizza.
