You jab at the pause button, freezing the screen. The resolution gets a bit worse, but everything's still fairly clear. Something's clearly been down there, and you definitely saw it...but what was it?
You peer even closer at the screen, then lean back and try squinting at it to see if it becomes clearer. You turn your head from side to side, pressing you ears alternately into your right and left shoulders.
If you press you left ear really, really hard into your left shoulder and squint in the general direction of the blob on the screen, it looks like...oh, dear. That's really not good.
