It was invented in 1930 in Toronto, Canada by employees of a company called JEM Rubber Co. They were messing with some of their scrap sheets of rubbers. The guy in charge of JEM Rubber went to Samuel Adams, who ran a practical joke company, but refused to take on the new idea claiming that it was too vulgar and would never sell. JEM then offered the idea to the Johnson Smith Company who sold it with great success.
In the 90's an advancement was made on the Whoopee Cushion, a springy foam was added into the inside of it so draw air into it. And the self-inflating whoopee cushion was born (Wikipedia is a good friend of mine)
So now I got myself a small whoopee cushion, about the size of my palm. It is easy to squeeze and laugh at. It relieves muscle tension in the arm and makes me laugh on most occasions when I'm feeling child-like. These envoke the relaxation response which is a good thing...
