According to Sky News, that bastion of common sense George W Bush has said we should be on the lookout for odd people. To quote:

"When people see somebody or know somebody who is exhibiting abnormal behaviour, you do something about it, to suggest that somebody take a look."

What sort of abnormal behaviour would that be, George? Perhaps binge drinking so much that your wife threatens to leave you? What about hearing the voice of God in your head? And how about invading a sovereign nation based on spurious and deceitful intelligence, causing a civil war and awful carnage in the process? Is that abnormal behaviour, you fatheaded fuckface?
