Lawyer's Revenge

A lawyer's dog, running about unleashed, beelines for the local butcher shop and steals a roast off the counter.

The butcher goes to the lawyer's office and asks, "if a dog, running unleashed, steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?" "Absolutely," the lawyer responded.

The butcher immediately shot back, "Good! You owe me $7.99 for the roast your dog stole from me this morning."

The lawyer, without a word, writes the butcher a check for $7.99. A few days later, the butcher, browsing through his mail, finds an envelope from the lawyer.

The contents read

"Consultation: $25.00."

Lyman C. Craig

Died 7 Jul 1974 at age 68 (born 12 Jun 1906).Lyman Creighton Craig was an American chemist who developed the counter-current distribution (CCD) method. Within five years of earning his Ph.D., he had designed and built a microdistillation apparatus (1936). Wartime research on antimarial drugs required identification of microgram amounts of an organic compound in a mixture, for which he devised a laboratory technique based on the distribution coefficient. He soon developed the CCD method for fractionation of complex mixtures with an apparatus that could simultaneously accomplish 20 quantitative extractions in a single step. A notable separation, from a difficult mixture, was the isolation and purified parathormone, the active principle of the parathyroid gland, achieved in 1960 with his colleagues. Craig also designed several other significant instruments, including his rotary evaporator, among others.«
