Why does a dog wag its tail?

Watched Wag The Dog with my friend today. Quite an interesting and funny show I must say. The movie is about the US president was caught in a sex scandal 2 weeks before the election. In order to resolve this PR disaster, they decide to create a fake war with another country so as to distract everyone's attention away from the sex scandal.

Its funny to watch see all the extreme measures they take just to divert the attention. And the way the media and the public actually falls for the trick.

I kinda like the quote that they put in the beginning of the show.

Why does a dog wag its tail?
Because a dog is smarter than its tail.

If the tail was smarter, the tail would wag the dog.

Great show. Should catch it if you can. Its a rather old show. Should be able to get it on DVD.
And perhaps can use those tricks in real life situtations. Create something fake to distract the attention away from something bad. Hmmm.....
