Stolen Car

A drunk phoned the police to report that thieves had broken in to his car.
"They've stolen the dashboard, steering wheel, break pedal, even the accelerator," he cried out.
However, before the police investigation could get under way the phone rang a second time, with the same voice came over the line. "Never mind," said the drunk with a hiccup, "I got in the backseat by mistake."

Joseph Black

Died 6 Dec 1799 at age 71 (born 16 Apr 1728). Scottish chemist and physicist who experimented with "fixed air" (carbon dioxide), discovered bicarbonates and identified latent heat. He lectured in chemistry, anatomy at the University of Glasgow, while also a physician. From heated magnesia alba (magnesium carbonate), Black collected a gas, carbon dioxide, different from common air. He published Experiments Upon Magnesia Alba, Quicklime, and Some Other Alcaline Substances (1756). Carbon dioxide was also released by fermentation, respiration, and burning charcoal so he assumed it was in the atmosphere. He also observed that ice melts without change of temperature, due to heat that becomes "hidden" - latent heat - and determined "specific heat" for heated of materials.[DSB gives date of death 6 Dec 1799. EB gives 10 Nov 1799.]
