Why Mr.4444 often asks me, "What's so funny?"

Lately, I have been very amused by The "Blog" of "Unnecessary" Quotation Marks, which posts random signs found in public places. Each sign demonstrates the inappropriate use of quotations marks, and Bethany's commentary consistently cracks me up. (Click on the pics to take you to the posts.)Which piece of punctuation, when misused, drives you crazy? Bethany also provides links to other blogs that expose the ills of society when it comes to signage. One of my favorites is Passive-Aggressive Notes.

[And I'm sorry for all of my unnecessary exclamation points that I use regularly, but I really am that cheerful, honestly!! (That explains all of my smiley faces, too :) ]
