Them's Fightin' Words

In my dream this morning, a boy was complaining to a man that his Halloween costume looked terrible.  The boy said of the man who designed it, "He's an apostrophe."

"Apostrophe!  Apostrophe!  The man's an apostrophe!" the man said.  Then two boys (in more professional-looking costumes) and another man appeared, repeating what the first man said.

Then the alarm went off, so I don't know what would have happened next.

Being called a punctuation mark would really get my dander up.
