The Hair of the Frog

"So did you kill the frog?"
-"Huh?"

"How did the hair twirl?"
-"What?"

This was asked to us by a friend of our family, the LEAST likely person I know to exaggerate or tell tall tales. He explained he and his wife's methods of predicting the sex of their babies 40 years ago, before all the technology we have now was available. Pat called it "redneck science." The biggest problem is that neither Pat nor I can exactly remember which way meant "girl" and which meant "boy."

1) Urine and a frog: Take a tiny bit of the pregnant mother's urine and drop it into a frog's mouth. If the frog dies, then that means it's one sex or the other. I seem to remember him saying the dead frog meant it's a boy, but I'm not sure.

2) Pluck a strand of the mother's hair, tie it in a knot, and place it on the mother's belly button. If the hair untied but was still in a curl, it was a girl (I think), and if it was straight, it was a boy.
