Jesus Nodder

I really can't improve on the description from the product page:

The Jesus Nodder is a plastic bobble-headed tribute to a remarkable man. Humbly dressed in common robes, Jesus stands 7-1/2" tall and offers a gesture of blessing with his hand. Put him on your dashboard and he just might inspire you to exercise patience and forgiveness on the highway. Comes in a window box with fascinating Jesus quotes and history.

I would also point out that you could look for indications of how certain prayers will be answered based on how Jesus' head nods, which would be nice to have around for just $7.50.
