Tuned Watermelons: I discovered that you could arrange watermelons AT the groc store and play them like a xylophone. The couple shopping nearby thought it was cool.
They were sniffing the cantaloupes.
I asked them if they knew how to detect a cantaloupe that had been inspected several times but then rejected by other people.
They said, "No"
I told them to look for several nostril impressions.
More things later ... maybe.
