Buy them some rubber stamps and some paper, then send them into another room to play.
Send them to a 'chick flick' I hear there's a new Stephen King movie out.
Send them to the pet store to look at puppies.
Give them $50 each and send them shopping
Tell them they look like they're getting fat and send them to the health club (this of course will cost you thousands of dollars before they feel 'thin' again)
Buy them a couple of snap together kits (the new VW Beetle and the Jetson's Saucer Car have lots of girl appeal) and let them work too!
Leave the house yourself and take your model with you.
Eat beans and.... they'll leave.
Belch a lot. They'll leave.
