A gentleman who simply couldn't believe it wasn't butter has proven that in fact it is, using his own personal lab in the spare room of his bungalow in Greenwich and two mice. He announced his findings over popular messaging service Twitter;
'It bloody is! I knew it. I'll get those cheating bastards. Selling me something that is what it claims it isn't'
Even before his findings were backed up by the more established scientific fraternity, the company that create the product admitted the truth.
'We basically created it to prove that people will believe anything,' stated founder and chief trickster Andy Claimer,'I mean it was yellow, salty, butter flavoured. It was butter.'
Some Workers at the 'I don't believe it's not butter' factory in Erith are appalled to have been part of such a scam.
'If I'd known I would never have worked there' said an employee called Geoff Creases, who would like to remain anonymous, 'It was my job to do the writing on the lids. I was the lie.'
However some conspiracy theorists refuse to believe the findings, such as Warren Domack of Hull.
'People are so easily fooled, I can't believe it's not butter actually is butter? I can't believe that. It's yellow, salty, butterlike. Far to similar to be the actual thing. It is a well known fact that butter is from Mars, humans simply cannot replicate it'
The company plans to continue trading but rename its product to 'I can't believe you believed it wasn't butter.' 'Well, it's true' stated a spokesman 'we can't.'
