Some eco-terrorists want to buy some giant's hogsweed.
"Don't you know that it is poisonous?"
"So?"
"Well why not go for some Japanese knotweed"
"Foreign junk"
"Or what about some water hyacynth... clog up a canal in no time"
Eco-terrorists don't have the attention span of a gnat. They have been eating too many magic mushrooms. They wander off to look at terricotta flowerpots.
They left with nothing... their brains as fluid as super refined sewing machine oil.
