I our primary we have those accordion room dividers. So I closed one half-way, and on the open half I hung black strips (that I made from cutting a plastic black tablecloth) to make it look like a jail. I put the mother's behind it.
Then I whispered to the kids a secret. And they were so quiet and paying attention! I told them that Stinky Pete had a weakness, if you sing really good and loud it actually puts him to sleep! So we sang some review songs for the program, and I added in a few reverent lullaby-ish ones too, and they sang so well! Every time they sang good he "fell asleep" and 1 mother would escape! The kids were thrilled each time to say the least, even senior primary got really into it.
In the end all of the mothers escaped and Stinky Pete was sad he just wanted his own mother. (The kids loved his fake cry.) So we sang a mother's day song to him and it made him happy. Then the kids all ran up and gave him a group hug. This part was cute, but not so reverent. Oh well, I learned that group hugs in church some times end up as a dog pile and that is NOT reverent for church!
