Say "Cheese!" - What is up with this face?

We're not too sure why Connor always pulls this face when we take a picture of him. Our digital camera has a tiny red flashing light that comes on right before you take the picture to help reduce red eye, so maybe he's squinting from that light? Here are a few pictures I've found over the last few months of this famous face. Jake and I can't help but laugh every time we look at them.
