Mispronunciations can be quite funny.

I misspoke.

So I’ve been working on a fairy tale novel (the Land of Four Seasons), and it includes a Prince with a magically sharp axe.

Since it is so sharp, naturally he isn’t allowed to use it until he’s old enough.  I was talking to a friend about this, but instead of ‘magic axe’, I ended up saying,

“Naturally, it isn’t until he’s old enough that they let him touch his magic ass.”
