Upon reaching 65, old Tom decided to retire. His wife suggested he go and do something to occupy his time, like join a club or get a hobby
Old Tom obliged and went out for a couple of hours. When he got home his wife asked about his day and he replied, "Oh, I joined a parachute club."
"What? Are you nuts? You're 65 years old and you're going to start jumping out of airplanes?"
"Yeah, look I even got a membership card."
"Old man, you need glasses! This is a membership in a Prostitute Club, not a Parachute Club!"
"Oh, great! Now what am I going to do? I signed up for 5 jumps a week!"

Vacuum cleaner

In 1901, a dust removing suction cleaner patented was filed by Hubert Cecil Booth, a bridge engineer (U.K. No. 17,433). Prior machines using compressed air created clouds of dust, but with no means of removal, the dirt simply settled again. Once struck with the idea of using suction, Booth made a preliminary experiment by placing a pocket handkerchief over the plush back of a seat. He put his lips to it, and after sucking, a ring of black spots on the handkerchief proved his principle. He started a mobile cleaning service. Built on a horse-drawn cart, his vacuum machine had an engine driving a pump provided with a long hose to extend into a house to be cleaned. An early task was to clean the great blue coronation carpet in Westminster Abbey for Edward VII's coronation.
