A man is having a quiet pint in his local bar when a hobo coms up and asks' Wanna buy this ferret for �50?'He puls it from his pocket.'What would I wanna buy that for?the man asked,This ferret gives the gobble of your life!!'the tramp says.The man thinks heis being conned,and tells the tramp to get lost.Undeterred,the tramp continues.'look,if you dont believe me ill let you take it outside for a free trial.'The guy then takes the ferret out to the back of the bar.Straight away,the animal unzips his trousers and gives him the best gobble job of his life.So the fella carries the ferret back into the bar,gives the tramp �50 and takes the creature home.When his wife opens the door.the man holds up the ferret,proudly,and says'Look what Ive bought for �50!'What on earth did you buy that for she squealed angrily.This ferret gave me the best gobble job ive ever had in my life!!'Well,says the mrs,what d'you want me to do with it?!' 'Teach it how to cook and then you f-off!!!!
