Question #1988

Geek Question of the Day: They may be (normally) fairly tiny, but I'm fairly certain that won't slow you down as I ask all of you; If you added or replaced the word 'mouse' (or 'mice') in the title of a story, what would the resulting plot and title become? As always, any source or genre is fair game!
