Offer, Retracted.
A good-looking guy is sitting in a bar, sipping a whiskey. He notices a gorgeous woman at the end of the bar, talking with a friend. He calls over a waiter, and sends them both a martini, along with a note asking for the gorgeous woman's phone number.
Ten minutes later, the friend walks over with a note. It reads:
"Unless you have a Mercedes parked outside, a million bucks in the bank, and eight inches in your pants, you're not getting anything from me."
The man finishes his whiskey, considering his response. He then writes this down on a piece of paper, hands it to the friend, and walks out:
"Actually, I only have about $300k in the bank; most of my net worth is in the three dozen buildings I own downtown. And today, I'm driving the Porsche; the Benz, Hummer, and Lamborghini are currently at my summer residence.
But If you think I'm cutting off two inches for you, you can fuck right off."

James Bryan HerrickBorn 11 Aug 1861; died 7 Mar 1954 at age 92.American physician and clinical cardiologist who was the first to observe and describe sickle-cell anemia. In 1910, he reported an unusual case he had examined. The patient was a 20-year-old West Indies student, attending a dental school in Chicago. "His illness had begun with malaise, pain in the back, the muscles of the legs and arms. He had a slight fever and was pale... he had suffered from a bilious attack... had vomited and... somewhat short of breath." In a blood test, Herrick found "nucleated reds were numerous [normal red blood cells lack a nucleus], 74 being seen in a count of 200 leukocytes [white blood cells]. The shape of the reds was very irregular... [with a] large number of thin, elongated, sickle-shaped and crescent-shaped forms." |
