Scientists have discovered that people with particularly long middle fingers are capable of increasing the severity of the traditional gesture of 'Up yours' to 'Fuck you, you lying twat'.
The discovery was made at the recent FIFA meeting where the hosting of the 2018 world cup was awarded to Russia. FIFA chairman Sepp Blatter said that the differences in gesture severity first became noticable when HRH Prince William's gesture was noticably more aggressive that British Prime Minister David Cameron who has a relatively short middle finger 'The Prince's gesture was a clear fuck you, you lying twat with knobs on, whilst Cameron's was more up yours you stupid tosser.'
'Hand gestures have been used for centuries' said Professor Thomas Boycott from Clare College Cambridge 'And it is clear throughout history that they are more effective when given by people with longer fingers. Winston Churchill, for example, had particularly short fingers, and to make them appear longer made his gestures knuckle-side towards himself. Many journalists thought that his attempt to tell then to fuck off and stop taking photographs was meant to describe some sort of innocuous V for Victory gesture'.
'Not all hand gestures are offensive though' added Professor Boycott 'For instance at 8 O'clock this morning I exited a side road on my bicyle and moved on to the main road, and a man driving a white van swerved and sounded his horn, and helpfully gesticulated that I should stop cycling and have a sausage sandwich with plenty of ketchup on it. Very kind of him, but how did he know I was feeling peckish?'
