Two elderly ladies had been friends for many decades. Over the years they had shared all kinds of activities and adventures. Lately, their activities had been limited to meeting a few times a week to play cards.
One day they were playing cards when one looked at the other and said, "Now don't get mad at me... I know we've been friends for a long time... but I just can't think of your name! I've thought and thought, but I can't remember it. Please tell me what your name is."
Her friend glared at her. For at least three minutes she just stared and glared at her. Finally she said, "How soon do you need to know"?

Largest hailstone

In 1970, a record hailstone fell on Coffeyville, Kansas, the heaviest authenticated one to fall in the U.S. in the 20th century. Its weight was recorded as 1-lb 11-oz (0.77kg) with 5.7-in (14.7cm) diam. It broke the old record from 6 Jul 1928 at Potter, Nebraska, for one weighing about 1-lb 8-oz (0.68kg), around 7-in diam. A newer U.S. record for size was set on 22 Jun 2003 in Aurora, Nebraska, when a hailstone was found about 7-in diam. (17.8cm) and 18.75-in (46.6cm) circumference. The world record was broken on 23 Jul 2010, by a hailstone found in Vivian, South Dakota at 1-lb 15-oz, (0.88kg), 8.0-in (20cm) diam., 18.6-in (47.3cm) circumference. A larger hailstone is said to have fallen on 14 Apr 1986 that weighed 2-lb 4-oz (1.02kg) during a hailstorm in Bangladesh that killed 92 people.«
