Peek-a-Boo
The first time looking at this photo, it doesn’t look like anything interesting happened. It looks like the photographer snapped a random picture on a bus testing their camera. For some odd reason, the picture shows an empty seat, someone’s blonde hair, and the fact they are on the road. But take another glance

Once you see it, you will never stop looking at it. If you haven’t spotted the odd occurrence in the picture, it’s a panda staring back at the camera. It is actually strange that a panda is looking back at the photographer through the rearview mirror. Does that mean a panda a driving the vehicle?!
