[HairOfTheDog]

Take a Hair of the Dog that Bit You.

After a debauch, take a little wine the next day. Take a cool draught of ale in the morning, after a night’s excess. The advice was given literally in ancient times, “If a dog bites you, put a hair of the dog into the wound,” on the homœopathic principle of “Similia similibus curantur” (like cures like).

Thank you. Love that link.

Except, though, you can't solve a problem with the same mind that created it.
