Must remember that B
A bit vulgar
A tramp looking for a hand--out calls into the priests house is invited in sat down in a front of a huge plate of sausages, and offered a bed for the night
He can't eat all the sausages and leave some on his plate - so he is shown to his bed
In the night he hears the bedroom door creak, and feels someone get in with him for the hospitality he says nothing
Next day, after he leaves he meets a fellow tramp looking for assistance - he tells him about the priests house
"Make sure you eat all the sausages though, otherwise they wait till you're asleep and shove them up your arse"
Sorry
