Mickey's Trailer (1938)

Walt Disney: Mickey Mouse

Quotes 

• Mickey Mouse : Hey, who's driving?

  Donald Duck : Yeah, who's driving?

  Goofy : Hyuck! Why, I'm driving.

  [realizes he's not, rushes back to the car, unknowingly unhooking the trailer, which rolls away down the mountain road] 

  Goofy : [thinking he's talking to the others still in the trailer]  The worst is over. It's all downhill from here.
