Be careful of your hair design.  Frank & Donald Smith of Orlando, Florida own the patent on a method for styling hair to cover bald areas using only the individual’s own hair — AKA, the combover. (U.S. Patent No. 4,022,227). Actually, the patent issued in 1977 and appears to be expired.

The Smiths were awarded the 2004 Ig Nobel Award from Harvard University for their contribution to the engineering field.

Other winners included the authors of a published report “The Effect of Country Music on Suicide” as well as Jillian Clarke, a Chicago high school student who investigated the scientific validity of the Five-Second Rule.
