It's been a long and gruelling season for Manchester United manager Sir Alex Ferguson, but the pressure on the Scot finally seems to have taken its toll, if a new video circulating the internet is to be believed.
For Sir Alex, whose team are favourites to retain their Premier League title, and are still in the Champions League, can be seen performing a crazy dance routine to the tune of the Tweets 1981 hit, The Birdie Song, in the new YouTube video.
Ferguson is accompanied in his well-choreographed jig by his assistant, Terry Phelan, but it's Sir Alex who takes centre stage. The video was filmed during last weekend's FA Cup semi-final defeat to Everton, and clearly shows his deteriorating state-of-mind.
Sir Alex's wife, Cathy, said:
"Oh, he's always prancing around the living room shouting about that Rafa fella, with that damned tweety bird song blasting out from his record player! He gets on my nerves!"
