The Sign

A boss was complaining in a staff meeting the other day that he wasn't getting any respect. Later that morning he went to a local sign shop and bought a small sign that read, "I'm the Boss". He then taped it to his office door.
Later that day when he returned from lunch, he found that someone had taped a note to the sign that said. "Your wife called, she wants her sign back!"

Benjamin Silliman Jr.

Died 14 Jan 1885 at age 68 (born 4 Dec 1816).American chemist whose report on the potential uses of crude-oil products gave impetus to plans for drilling the first producing oil well, near Titusville, Pa. Silliman separated the crude oil into its component parts, or its fractions, and observed the characteristics of each fraction. He determined by use of a photometer that distilled petroleum burned much brighter than all but the most expensive and least efficient fuels. He also noted its potential use as a lubricant; he found it capable of withstanding extremely high and low temperatures and able to keep its form after long use. Silliman concluded petroleum was “a raw material from which...they may manufacture a very valuable product.”His report marked petroleum as the answer to the illumination fuel crisis.
