Oh, here's another lobster story.
Many years ago, on a fly-and-drive trip to Boston I decided to make a tour of the New England states. When stopping at a grocery store somewhere in New Hampshire to get provisions, I saw that they had live lobsters in a tank, and that they would steam the order for us.
So, on the spur of the moment, I bought two big ones. But now, we had to bring it back to the hotel room to eat! No problem.
Well, it turned out these lobster shells were harder than any we had had. Very hard to crack. Uh Oh! If I were driving my own car rather than a rental, I would have some mechanic tools to crack these lobsters, but here I was completely helpless.
We managed to crack them open in the end somehow. I think I used a wine bottle.
