Meaningless trivia moment - Flipper's signature call wasn't a dolphin sound; it was a sped up recording of a kookaburra.
"Kookaburra sits in the old gum tree
Merry merry king of the Bush is he
Laugh, kookaburra, laugh kookaburra
Gay your life must be"
Well, there ya go, I did not know that .. thank you

Thanks, gunna being singing that one in my head all day
