My Mom put some keys on her Christmas tree and sent the kids off to find them. When they brought them to her she said:
Mom: What's the "key" to Christmas?
Z: These keys from the tree!
Mom: I mean, what is the main reason for Christmas?
Z: Santa Claus!
Mom: No, I mean whose birthday is it?
A: Mine! (it's true... her birthday is the 27th)
Mom: Who else?
Z and A: Jesus!
