Can you spot what is wrong with this picture of an orb spider in its web waiting for prey and explain why its wrong?

The spider was on Cannabis when making the web?
Even more bizarre webs can be observed when the spider has been put on a "diet" of cocaine, speed, heroin, ..

Erm, no, I don't think this spider was 'high' on anything but its web. Nor had it been irradiated or had the L'Oreal treatment. (It wasn't worth it!)
-
I thought that orb spiders tended not to sit at the center of their webs whilst waiting for prey. It makes them too conspicuous to predators, so they tend to sit at the edge of the web instead.
-
Nope. This is a common garden spider. They are usually found in the middle of their web.
-
Here's another, with the same problem.

Nobody got it yet???

Shouldn't the spiders be head down, rather than looking skyward ?, (i.e. pictures are upside-down).
-
You got it RD.
So does anyone know why spiders sit head down in their web?

Cos they don't make Ray-Bans (http://en.wikipedia.org/wiki/Ray-Ban) small enough ?. [:)]
Edit: "John Lennon" sun-glasses are apparently available in spider size ...

er, well, um, maybe so they can drop on a silk thread released from their abdomen if they need to make a speedy exit or drop onto their prey?

To keep from fainting?
I think that the "John Lennon" sun-glasses spider from RD is one of those jumping spiders I admire so much.
I hope you admire them from a considerable distance!
Most spiders have poor vision, could this be a factor in their habit of facing down?
