When people keep asking to borrow things from Mickey, he realizes that he has trouble saying "no" and turns to Donald for help. But when he finally begins to say no, Mickey finds himself in a slew of even worst trouble when he is arrested for running a stop sign and doesn't yield to the police when they order him to pull over, refuses the oath to tell the truth in court, and ends up in jail. His cellmate's question about his prison uniform forces Mickey to break out of jail and escape, but as the police look for him, Mickey returns to what's left of his house to sob over how saying "no" got him in so much trouble, only for everyone who borrowed something from him to return it with compensation to boot for some of them, such as Scrooge returning the money he borrowed with interest, the Three Little Pigs adding a second story to Mickey's house, and Figaro providing a friend for Mickey's goldfish. When everyone asks if they can join Mickey and Minnie to watch some TV, wondering if he minds at all, Mickey replies that he does mind, finding another means to say "no" that won't cause him problems.

- This episode shows that Mickey Mouse does not know how to say "No" in this series, but he has said "No" various times in many of his previous appearances, including some previous episodes of this series. It is possible that this episode took place before those ones, or Mickey was just bluffing.
- This could be likely to be a goof or this episode is non-canon, but it looks like maybe they just made this short just to get funnier.
- This is the first appearance of Mortimer Mouse and in this series.
