Cute ideas! I'd include:
~Night off from walking the dog
~Night on his butt (ie: I'd fetch his drinks, phone, etc. so he doesn't have to get off the couch!)
~Favorite restaurant night (I HATE his favorite place, so its a big deal for him to drag me there)
~Freedom to fart night (without me complaning )

Oh goodness... I could come up with a trillion if I sat here!
