Lol tell ya a funny story about that:
Back in 2008, i was in London with my wife and we had visited a hookah bar and liked it so much, that she bought a small one and a big bag of shisha ( wet tobacco) from a local arabic shop. We had taken the Eurostar to paris one day on the trip and visited Pere LeChaise cemetery while there and she without my knowledge, collected soil from Jim Morrison's gravesite and placed it into a small baggie.
Fastfoward to returning back to the US and we were going thru customs. I told her " you dont lie to them but dont say anything more than you need to as far as what you're carrying back home" because we had more alcohol than what was allowed. Anyways, she gets up to the Customs officer and declares " I got a shisha!" ( she meant hookah but declaring either raised suspicions despite being legal). The officer said " Whats that?" And she begins describing a hookah perfectly. He goes " Oh really? Well congrats you've been designated for a random bag check". He then took our suitcases and flung them across the floor and and had all of our stuff strewn all over.
He began berating my wife about the hookah and i said " Look sir, its just tobacco and you can swab it" he got mad but realized i was right but then found the bag of Morrison dirt which looks VERY much like some hash. The problem here is you arent allowed foreign soils or fruits and veggies. So i just kinda sunk and said " F%ck it, im screwed" before my wife chimes in " Ah thats the dirt from my extra pair of sandals!" He goes " Oh, well clean your shoes next time" but threw the bag back in.
Somehow we made it out before getting a cavity search or him noticing the excessive amount of booze lol
