Sod is a funny word - I brought one back through Holyhead, during the 'security' times, wrapped in newspaper. I got stopped and the bag was being emptied out, I was managing to explain everything as it appeared - until the nice English customs chap pulled the wrapped item out - What's in here? - I could only think of 'sod' and it is just not a polite word on this side, so I hesitated, he became immediately suspicious and carefully unwrapped it, breaking off a bit of the brown, fibrous matter and sniffing it - I think he could smell promotion, his mates standing behind him were well aware of what it was, but were just laughing amongst themselves at him. I managed to explain satisfactorily and was released....
He never noticed the Holy Water.
