That's a sailfish, not a swordfish. Fastest fish in the sea.

I hate Illinois nazis.

A string that long that doesn't sag to the ground or break is already physically unlikely, but assuming it exists it would probably stretch enough to compensate for the movement. So I'd say no, unless you had a perfectly rigid string.

But he's a liar and I'm not sure about you!

Thanks for getting a great song stuck in my head.
