Shalom Race

As you may know, in a shalom race the skier must pass through about 20 "gates" in the fastest time. Well, it happened that Israel had the fastest slalom skier in the world and had great expectations for an Olympic gold medal.
Came the day of the final, the crowd waited in anticipation. The French champion sped down the course in 38 seconds. The Swiss in 38.7 seconds, the German in 37.8 seconds and the Italian in 38.1 seconds. Next came the Israeli's turn ... the crowd waited, and waited...six minutes!
"What happened to you?" screamed his trainer when the Israeli finally arrived. Replied the exhausted Israeli: "Which of those idiots put a mezuzah on each gate?"

Elizabeth Gertrude Knight Britton

Died 25 Feb 1934 at age 76 (born 9 Jan 1858).American botanistt known for her lasting contributions to bryology, the study of mosses. She went on numerous botanical expeditions to the West Indies and in wilderness areas of the Adirondacks. A visit to the Royal Botanic Gardens at Kew, near London, England, made a great impression on Britton and she determined that New York City should have its own botanical garden. She was the driving force in the establishment of the New York Botanical Garden in the Bronx. The original 250 acre garden was incorporated in 1891. Through publications, lectures, and correspondence, Britton also raised public interest in conservation issues and promoted legislation for the protection of endangered native plants.
