In all the years my father worked for Ralph David Leibowitz , once did our family every hear dad "Blow his top".
Seems in 1958, dad was the toy buyer (in addition to a lot of other stuff) for Ralph's 5, 10 and 25. At a toy show in Chicago, dad bought 100 gross (yes 14,400) Hula Hoops for the six stores. When Ralph found out, he was furious.... something about "How could you do something so stupid!"
Dad came home early that day and told mom, "I quit!"
A day later, Ralph came over to the house and apologized over and over... they sold the 100 gross of Hula Hoops in a matter of two days!
Dad tried to buy more... nothing was available! Guess he should have bought 1000 gross!!!
The Hula Hoop® toy is the most popular American toy ever made. It is a brightly colored hoop of plastic which is rotated round and round the body by moving the hips. The toy was introduced by Wham-O Manufacturing™ in 1958. It cost $1.98, and it was so popular that stores kept running out. In the first six months, Americans purchased 20 million Hula Hoop toys. In 1958, 100 million were sold worldwide. All over the United States, people held Hula Hoop contests to see who could spin the longest.
The hoop is an ancient toy. It existed in ancient Egypt, Greece, and Rome, and in 14th century England. (Of course, they didn't have plastic then.)
Only problem with these things is that you needed hips to keep 'em up!!!
