What would you do if a customs official welcomed you to a foreign country with a "KISS"? In a manner of speaking, that's exactly what happened to me today as I arrived in Seoul for a series of meetings and -- like so many other travelers before me -- answered a series of mind-numbing questions from a group called KISS (the Korean Immigration Smart Service) before I could enter the country. Questions included: (1) "Are you carrying a crossbow, explosives or poisonous radioactive substances?"; (2) "Are you bringing opium, heroin, cocaine or other illicit or potentially dangerous drugs such as diet pills into the country?"; (3) "Are you transporting endangered species such as tigers, cobras, turtles, crocodiles or bear's gull into the country?"; and (4) "Are you carrying any pornographic materials such as books, CDs or photos into the country?" I fought the impulse to laugh -- "Yes, my crossbow is in my carry-on bag, right near my supply of uranium which I take purely as a dietary supplement ..." -- and just answered "no" to everything. After all, joking with a customs official is usually the KISS of death in any country ...!
