Blimey, cupid! It would take a month to smoke a Basking Shark. Perhaps you could plug it's enormous maw with a couple of hundred Benson and Hedges, but I don't think they'd light very well under the ocean!
All the same, I don't think you could eat it in one sitting....
I didn't think Basking Sharks attacked? I've only seen them on the tele, but they look a bit toothless. Perhaps they sidle up and give you a nasty suck - gumming you to death!
Ooh, nasty! Death by "ee' by gum"!
