McPherson walked into a bar and ordered martini after martini, each time removing the olives and placing them in a jar. When the jar was filled with olives and all the drinks consumed, the Irishman started to leave.
"Excuse me," said another bar patron, who was puzzled over what McPherson had done. "What was that all about?"
"Nothing," said the Irishman, "my wife sent me out for a jar of olives."

Aerosol

In 1941, a patent for the first aerosol can used in a commercial application was filed by chemist Lyle D. Goodhue and entomologist William N. Sullivan, researchers at the U.S. Dept. of Agriculture. It was titled a “Dispensing Apparatus” (U.S. No. 2,331,117, issued 5 Oct 1943). To apply oil-free insecticides in mushroom houses, they dissolved an insecticide in a nonflammable, liquefied gas under pressure in a strong steel container. The insecticide was allowed to escape in a fine spray through an oil burner nozzle. During WW II similar cans, dubbed “bug bombs,” were used to protect troops from malaria-carrying mosquitoes. Under the public service patent, royalty-free licenses were issued for the manufacture of insecticidal aerosols until the patent expired in 1960. Many improvements followed.Image from 1947 ad for Westinghouse household Bug Bomb.
