Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.
As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.
The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.
When questioned about her choice, the blonde replies:
"Well, if I get hot, I can roll down the window!"

Johann Georg GmelinDied 20 May 1755 at age 45 (born 10 Aug 1709).German explorer, natural scientist and botanist who acted as a natural historian on the imperial scientific expedition led by Friedrich Müller ineastern Siberia (1733-43). From barometric pressure readings, he was first to determine that the shores of the Caspian lay below sea level. In 1735, at the town of Yeniseysk, he recorded a record low temperature. He also detected the permafrost in eastern Siberia, which, a little way below the surface of the ground remained frozen year round. Gmelin spent the period 1747-69 preparing a book recording his finds there. InFlora sibirica sive historia plantorum Sibiriae, he detailed 1,178 species and provided 294 illustrations. His original degree was in medicine (1727), but his fields of study included chemistry, natural resources, geology, zoology, ethnography and geography. He was Leopold Gmelin's great uncle.« |
