Ten Dumb Inventions That Made People Rich

\Airborne
This overhyped vitamin supplement, first marketed in 1997, may do nothing to prevent illness and has recently suffered quite a backlash, yet its creator, former schoolteacher Victoria Knight-McDowell, is now living it up like a virus lives it up insideEdward Cullen. 
Antenna Balls
Ever since these smiling eyesores, originallythe idea of gas station Union 76 but later made popular by hamburger chain Jack in the Box, took off in the mid-1990s, many savvy entrepreneurs have made oodles of cash simply by adding two cents' worth of paint to a foam ball. 
Big Mouth Billy Bass
This irksome plastic novelty, released in 2000 by the evil geniuses at Gemmy Industries, has made more money from a singing career than nine-tenths of Hollywood. 
HeadOn
This hot-selling homeopathic headache reliever, whose belligerently repetitive ads went viral in 2006, illustrates one of the most important principles of holistic healing: You don't need any active, or even effective, ingredients to legally sell your product. 
OxiClean
Made from an active ingredient anyone can buy at a pool supply store, OxiClean -- released in 1999 and popularized via famous infomercials featuring now-deceased pitchman Billy Mays -- proves that people who clean all day don't always understand science. 
Santa Mail
For roughly $9.95, your child can receive a "personalized" reply to his or her letter to Santa. If he wasn't so jolly, the real Santa would probably take offense to the many companies profiting from his good name (and penmanship) in this manner. 
Slap Chop/ShamWow! (tie)
These essentially useless products, hawked in ubiquitous infomercials since 2007 byactor Offer "Vince" Shlomi, show how far a good pitch can go. One is an expensive towel, the other actually adds a step to the process of cutting vegetables. 
Snuggie
Wearing your clothes backwards has never been so marketable. Buy our new backwards sportcoats -- no need for a tie! 
Pet Rock
Topping our list is the granddaddy of all successful novelty items: The pet rock,conceived of and sold by Gary Dahlbeginning in 1975. Yes, a rock that you keep as a pet -- and over 5 million people bought it! Our parents were really stupid.
