Hallowntine

Recession Valentine:

1 whole mackerel: EUR1.60
Role playing with the mackerel: 45 minutes
Autopsy of the mackerel: study of the digestive system (from point of entry to point of exit), respiratory system in fish, reproduction: 15 minutes
Filleting of the mackerel: 3 minutes (I haven't quite lost the touch)

Valentine present for Mum: "here Mum, a mackerel's heart, for Valentine, love XXX LUCA"
Present for all the Six Sigma teams of the world: "hi guys, this is what a brain look like. It's small. It's a mackerel's brain. But it contains more brain cells than what you have connected together in your endless fruitless meetings, love XXX Mimi"

The fillets were eaten with chips.

The heart and brain will go to the deep freezer until next Halloween.

The anatomy lesson will stay with them forever.
You may as well show them the inner workings of life when they are young and do not know yet what squirmish means...
