So, What do you do???

It seems that some nights are more difficult than others at bedtime. I've always struggled because I think kids should go to bed when their children tell them to. Often my two youngest Luke and Regan get the giggles and I cannot settle them down. Some nights it goes on for hours and Todd and I start out very kind and end up quite angry. Tonite I'm doing something different. L and R did not seem to be settling down so I decided to invite them downstairs to do a little cleaning. It's 8:55pm and they still seem pretty excited. They're cleaning my baseboards and dusting. When they're done with that the windowsills are calling their names unless they decide to go to bed. And me, well I'm sitting here telling them to be quiet and keep working while fooling around on the computer. I don't know if this is a good idea or not but I'm sure not getting mad and the house seems to be getting a little cleaner.
So...what would you do???
