Interpretation? They have a worm fiddling/worm calling contest in the UK every year.
This UTube video doesn’t allow embedding, but here’s the link to a scaled down version of the contest.
The winner, a young boy, collected 290 worms in 30 minutes.
290 worms equals 24 dozen times $3.00 a dozen for fishing worms equals $72.00 for 30 minutes work equals $144 an hour. This young man has the talent for a nice little business.
