A man reads that there is a talking dog for sale,and as he's looking for one he goes to visit it!
The dog's owner let's the man in and shows him the dog who nods and says 'Hello there, my name's Paul,' and quite rightly the man is flabbergasted.
'Anway,' continues Paul, 'I've won Crufts 3 years running, I've spent time in Afghanistan with the troops sniffing explosives, been on numerous TV adverts and ran the London Marathon for charity last year.'
The man is mesmerised and turns to the owner, 'Why are you selling him?'
'He tells lies,' says the owner.
