My friend Larraine sent me a link to this site the other day. It is amazing. If you're into weird and absurd inventions, then it is a great source for inspiration and a good laugh. The descriptions given for each invention are very entertaining and surprisingly informative in some cases. Go check out The Patent Desk.
Here is a sample of what you're missing if you don't click on that link:
Mustache Guard


Inventor: Charles A. Steele Junior
Patent number: 927892
Filing date: Feb 17, 1909
Issue date: Jul 1909
Beautiful illustration for a mustache guard from 1909. At the time gentlemen would apply wax to help mold and shape facial hair. Of course this would cause problems when a hot drink was sipped, the steam would melt the wax causing it to drip into the cup and exotic drinks could stain the hair. Mustache cups usually had a ledge or guard across the cup, this model however is separate and can be clipped on to any cup or glass. During the recording of Sgt. Pepper’s Lonely Hearts Club Band, John Lennon drank his tea from a mustache cup. At the time all four Beatles were sporting mustaches and the record even included a cardboard cut-out mustache designed by pop artist Peter Blake.
