This is the same technique I used with my children when they tripped on a chair leg, or hit something by accident and started crying. I would address the offending chair (or whatever), shake my finger at it and tell it how bad it was, then tell it it would have to be punished and put it in the corner, or tell it it couldn't talk to anyone for the rest of the day, or whatever ridiculous "punishment" I could come up with. Always got the child laughing instead of crying.
