Lommy, while you're on, this is the moment to tell you that marine biologist's joke I promised you before we set out, lest I forget. (If you don't get it, ask a Brit to explain.)

The squid had a few too many last night and is having a huge hangover. His brain (or whatever squids use instead) hurts, he's feeling squeemish, he can't control his tentacles properly, he's having a really wretched day.
Swimming by comes a dolphin, he says to the squid: "Poor you, you look really bad, but I tell you what, all you need is some fresh water. Hang on to my fin, I'll take you up near the surface where there's more oxygen - that'll do you good."
So the squid hangs on to the dolphin's fin, and the dolphin takes him up near the surface where they meet a shark. Says the dolphin to the shark, "Hi mate, here's the sick squid I owe you!"
