Beware cigar boxes!

Upon our recent return from Cuba (Snoopy Goes To Cuba Tour - 2010) one of us, who shall remain unnamed, attempted to bring three empty cigar boxes into the US in order to store pen and pencils.

Meanwhile, recent revelations of FBI interrogations of visitors to Cuba got me wondering...then I saw the following article and it all become clear to me.
