A man walks into a fish and chip shop and asks for cod and chips.
'Sorry mate, we've run out of cod.' says the assistant.
'Oh!' says the man, 'In that case i'll have cod and chips please.'
'I told you, we've run out of cod. We've got haddock or sausages!'
'Oh! Ok, i'll have cod and chips then.' says the man.
The assistant is getting cross.
'Look...we haven't got any cod.'
'Right, i'll have cod and chips instead then.' says the man.
By this time the assistant is losing his temper.
'Look mate, tell me...how many f's in haddock?'
The man replies,
'There are no f's in haddock.'
'How many f's in sausages?'
'There's no f's in sausages.'
'How many f's in cod?'
The man replies, puzzled,
'There ain't no f in cod.'
'That's what i've been trying to tell you!!!'
