The best Halloween costume is one that is a great idea but not too much work. Like the following:
This year I have THREE Halloween costumes, first I was an MSN butterfly for the Studly Hubby's NERD party, then for work tomorrow I will be that dude who got pregnant (Thomas Beatie), and on Saturday I will be a doctor (so I can wear a mask and gloves and protect myself from all the germy kids while handing out the Halloween candy).
Happy Halloween everyone!!
