I really prefer [b]Don’t go to the office day[/b]

followed by: Pants optional day
Bring your funy ass to the home office day
Shower optional day
Forget about the dishes day
“I wonder what the crud on my teeth is?” day
Learn your coffee vs. shake tolerance day
“How long can I afford to do nothing?” day
Nude editing day
Post crap to your blog all day, day

but those are just a few of my favorites.
