Puns: they catch you like a fish

       My son was talking about volcanoes he'd enjoyed going over on his way to Seattle in an airplane.

       And he said, "You know, there's a whole series of them," and he said "which you'd expect--they'd be in a row--they're a fissure in the earth."

       And I said, "I thought fish're in the sea."

       He-he.  Caught him unawares, and he said, "Ooooh," and laughed, and of course I did, and my wife's face went all sour because we'd made a lousy pun.

       But we liked it, and it was a good one.
