When I was younger and used to fish the Thames at Hampton Court bridge, much mirth was had with maggots. One of the main irritations in fishing there was open top pleasure boats that came past too close to the river bank, forcing a rapid withdrawal of tackle (
). In these instances, the catapault would be loaded with a full cup of maggots and they would be fired into the offending craft.
Such fun watching chinless toffs in silly hats leaping round a boat screaming obscenities. Happy days.
