BBC television news has an item about "legal highs", which reminded me of a trip I took to Amsterdam a few years back.
I was amazed to find that some of the 'head shops' sold small-dose tablets of various drugs which you could buy for your pet - the idea being that you and your dog or cat get off your heads together.
I went inside to look around and heard a young customer at the counter.
"Excuse me, man" he said, "how much is that dog 'E' in the window ?"
