(1) - Once upon a time, there were some small goldfishes cycling in their jar. Then one says to the other :
° Hey Marco, didn't we alreday passed this
(2) - pot of gold ?
(1) - HOUSE !
° I don't know Polo. Actually, I don't remember what we did five minutes ago ...
° Yep, stupid GoldFish memory ...
(1) - Ten minutes later :
° Hey Marco, what should we do during the next hollidays ?
° I don't know Polo. Maybe we can cycle in the other way ?
(3) *forced laugh* Ha ! Ha ! Ha !
(All) - ...
(2) - I met someone last day ... but I don't remember where, why, nor who it was ...
(All) - ...
(2) - I remember now ! It was ...
(All-2) - We also remember him, and we don't want to hear about him !

Morality :
GoldFish memory is a plague that run everywhere in the world ... but I don't remember from where it has started.
