SearchResearch Challenge (3/22/2017): There's a fly in my...

Every so often you pause and say "What??"  

This happens to me fairly often, perhaps more often than you'd think.  One of those times was a couple of week ago when I was using the "facilities" and saw this in my field of view: 

"That's odd..." I thought, "why is there a bee in my urinal?"  

Here's the stepped-back view.  

This is the kind of unusual, a bit odd, and definitely strange thing one needs to memorialize in a picture.  A quick glance around, and I got the shot.  

Then just a few days later, I found THIS:

As I said in an earlier post, travel is broadening...  

We run across mysteries on a daily basis, and our curiosity drives us to ask questions... Such as this week's set of questions that came up while travelling.  

1.  Why are those little images in the bottom of the urinals?  What were the bowl designers thinking?  (Just contemplate that for a moment:  Somewhere there is a designer who designed this.  What's their motivation?)  

2.  On a different note, I got this two scary looking screens (below) popping up on my Nexus 5 Android phone not long after taking these photos.  Should I be worried?  What (if any) action should I take? (I'm already suspicious because I don't recall visiting any "adult sites.")  

3.  While traveling in Norway, I found the sign below on a tram.  What's this sign all about?  (I don't read enough Norwegian to figure it out.  Can you?)  Remember that you can click on the image to see it at full-resolution.

Be sure to tell us HOW you figured out these answers.  (These should be pretty quick and fun.) 

Enjoy.
