border crossings: USA/Canada

[Adolf Ceska]

Apologies for the following joke.

My friend Ron Walker, an excellent amatuer botanist, was a custom officer
on a small USA/Canada border crossing in south-central British Columbia.
One day a hippie-like guy was crossing the border with bags of dried
plants and he claimed that he was a herbalist.

"Open this bag," asked Ron.

The guy was hesitant to obey, but he eventually opened the bag and said:
"It's not what you think it is."

"Do you want to tell me that this is NOT Verbascum thapsus?" answered Ron.
