Hilarious joke

Q: Why is the Government like an Ikea wardrobe?

A: One loose screw and the whole cabinet falls apart.

The thing I really don't understand is this: who in their right mind would want to sleep with John Prescott? And that implies that The Office Of The Deputy Prime Minister only employs the insane. Doesn't make one feel too confident about the government, does it?

The lunatics have taken over the asylum.

Now, here's a question for you. The hilarious joke: the two lines at the top of this post or Mr Prescott himself? Answers on a postcard, please...
