CountryEntertainment, my mom used to use that technique on Dad.  If she wanted a room painted, she'd buy the paint, move the furniture, set down the dropcloth and take a couple of swipes.  Dad would be on it in a flash, telling her that it had to be done "right", and that he would take over.  
I think that's a great technique - it shows a willingness to actually do some work yourself and it saves both you and your DH the pain of nagging.
