Politicians are like the weather.
Nothing can be done to change them.
Politicians are like food processors.
You need one, but you're not quite sure why.
Politicians are like commercials.
You can't believe a word they say.
Politicians are like popcorn.
They satisfy you, but only for a little while.
Politicians are like nappies.
They need changing regularly and for the same reason.
Politicians are like Violinists.
Always on the fiddle.
