hate to be a pedant but there is a brand of duct tape called......duck tape
Ha really? I assume that originated from the common mis-pronunciation though, right?
Actually, Duck Tape is the original name as it was duck cloth cut into strips and covered in adhesive.
It's duct tape that came around as a result of mispronunciation

Etymology
The origin of the name of the product, "duck tape" or "duct tape," is the subject of some disagreement.
One view is that it was called "duck tape" by WWII soldiers either because it resembled strips of cotton duck (canvas) or because the waterproof quality of the tape contributed to the name, by analogy to the water-shedding quality of a duck's plumage. Under this view, soldiers returning home from the war found uses for duck tape around the house where ductwork needed sealing. Other proponents of this view point to older references to non-adhesive cotton duck tape used in Venetian blinds, suggesting that the name was carried over to the adhesive product. The Oxford English Dictionary says that perhaps "duct tape" was originally "duck tape". This view is summarized most notably in a New York Times article by etymologist William Safire in March 2003. Safire cites use of the term "cotton duck tape" in a 1945 advertisement for surplus government property.[18] The Brooklyn Daily Eagle uses the term "duck" in 1902 quotation for "100,000 yards of cotton duck tape" being used to protect the cables of the Brooklyn Bridge.[19] Thus a fabric duck tape was available to which an adhesive could have been added.
