PLEASE EXPLAIN.

CAN SOMEONE PLEASE EXPLAIN THE PHENOMENON OF SHOES HANGING FROM ELECTRIC WIRES?

Quite often when I'm driving down a street, I see a pair of jogging shoes hanging from the center of electric wires.  No matter what city I'm in, there will be a smattering of these across numerous suburbs.

No one has been able to explain why this is.  So, I am going to put forward some theories of my own.  I am eager to hear from anyone who cares to give their explanation.

1. Is it a sign of an alien abduction?

2. Do possums have a secret agenda?

3. Is it a clever nesting place for birds in order to hide their chicks from other predatory birds?

4. Is it a political statement?

5. Is a cult behind it?

6. Is it subliminal advertising designed to make you think about buying shoes?

7. Is it a secret code?

8. Why do the shoes always end up at the center of the wires?

9. Was someone in them at the time they were put there?

10. Why waste a good pair of shoes?

11. Did the shoes stink so much that throwing them onto the wires was the only place to get rid of them?

12. Were they thrown by a drunk who, in spite of inebriation, had superb aim?

I really want an answer to this question as it causes me no little mental anguish.  Actually, none at all, but it is curious.
