This is a great idea to use with children when getting ready to leave a store or shopping mall.

The Fun Train
This continues to work 95 per cent of the time. When it is time to leave, I say, "time to go to the fun train (which is our vehicle) . . . all aboard." I'll call the children by name and we walk behind each other, "choo-chooing" to the fun train. My five year old told me that I am the conductor and we now need pretend tickets for the fun train. I'll usually only need to announce boarding twice before the little patter of feet are chugging along.

This idea came from a therapeutic child web site.
