I used to work on the U.S. Canada border...many tales of fear and loathing...one day they left about a 15 lb. block of hashish in front of me, I was sorely tempted to break off a wee bit purely for scientific purposes of course.
One of the top attractions of the job was when the customs guys spoke to travelers coming in from Canada, "did you bring back any of those nice Cuban cigars?" they'd ask nicely. Yes, yes we did! OK, give them to me, you can't bring them in.
Then they'd call me at my office across the parking lot...hey buddy, come on over, we've got some fresh Cubans to smoke, and smoke them we did.
