Beautiful.
My favourite is the episode with Robin Williams and the dolphins.
I like very much Operation Lemur too (with John Cleese).
So is mine!
Actually, it's the only one I remember at all. But still, I saw it a lifetime ago, in the past millenium ;) - and I can't forget it.
It was so cute and heart-warming and beautiful.
I especially liked the way he and the she-dolphin (a dolphiness? ;)) in the swimming pool communicated by telepathy, it seems.
And the way the other dolphin, underwater, swam up to him and "KISSED" him - and then again, as if to remove his doubts... ;)
And Robin's comments, of course...
(Remember him swimming past a group of dolphins and commenting how they looked like a group of teenagers making fun of his outfit? :))
It's a LOVELY programme.
