That Musee du poisson d'avril reminds me of - tongue in cheek -describing to a young skydiver how tough it was to skydive back when I started during the 1970s.
We had to hire pterodactyls to carry us aloft and you needed a basket full of fish to convince them to climb. Th emore fish, the higher you could jump from. The secret was in flicking your wrist just the right way to sail the fish ABOVE the beak of the pterodactyl, to convince them to climb a few more yards.
Note: this was long before metres were invented.
Hah!
Hah!
