Fish-eye lens

I took the car in for some work this afternoon, and as usual, went to commiserate with the bored fish in their cramped tank while I waited. A couple of the residents found the camera's eye on the far side of the glass interesting.

"Ohh! And who are you, and how did you get out?" 

"Looks fishy to me!"

And then I got the car back and went out into the sunshine. While the prisoners in their tank swam round and round, back and forth. If they were lions, they'd be pacing.
