Happy National Dress Up Your Pet Day

According to my 2008 Petsmart calendar, today is National Dress Up Your Pet Day. Had I a pet would I be partaking in this festivity? Probably not, unless I had a Halloween costume handy (or a Bowser costume). But since I currently have no pets, I'm not faced with the dilemma. I perused the calendar for the next few months, and all the other holidays listed are normal ones, so I guess that means this holiday is (somewhat) legit. Anyone partaking?
