A German friend of mine gave me a Muntser cheese once when we were over there. It had come out of his fridge and I, being English and in complete ignorance accepted it gracefully. He smiled a lot as he helped me pack it, it was a little whiffy but he said they were like that but that I would enjoy it.
We got to the airport check in, by this time my baggage was so high it could have flown home on it's own. He was grinning from ear to ear, the Swiss check in girl jokingly said " your aftershave aint cutting it Mr C". My Deutsche mate was almost apoplectic at this point, I called him a bast**d, we all said our goodbye's etc and swmbo and me boarded the plane.
As we came through customs in UK I saw a large sign telling me "no soft cheeses" among the other forbidden items.
The bag was by this time whistling and looked decidedly swollen to my eyes and I reckoned anyone opening that zip would pay dearly.... along with the rest of the customs staff and passengers... this was indeed a 'dirty bomb'!
I walked past a custom official, as I passed, probably looking guilty as sin, I saw his head swing round and he fixed me with his gaze. Amazingly he didn't stop me to search my baggage.... I wonder why.
To this day, I believe that bloke knew exactly what I'd got in there but I expect he had come across this before and once he had experienced the process of confiscation he had probably vowed never to stop anyone with a bag smelling that bad.
As a sub note, despite the filthy disgusting odour, I was determined to taste this 'thing' just so I could honestly say I had done so.... it was absolutely foul, it tasted exactly like it smelled.
If the Luftwaffe had loaded this cheese into their 500kg bombs and dropped them on London it would have been game over for us as we would have deserted in droves to the counrtyside... upwind of London!!
