What the he11 is "duck tape"? Are you taping up ducks? There is a "Duck" brand of duct tape, though...

I used to think "duck tape" was a misnomer as well until I found out it actually
was originally called "duck tape" by the military, who were the first users of the product as we know it today.
From Wiki:
"
The Revolite division of Johnson & Johnson made medical adhesive tapes from duck cloth, beginning in 1927. During World War II, a team headed by Revolite's Johnny Denoye and Johnson & Johnson's Bill Gross developed a new adhesive tape for the US military, intended to seal ammunition cases against moisture.[11] The tape was required to be ripped by hand, not cut with scissors. According to Johnson & Johnson, the idea came from an ordnance-factory worker—and mother of two Navy sailors—named Vesta Stoudt, who worried that problems with ammunition-box seals would cost soldiers precious time in battle. She wrote to President Franklin D. Roosevelt in 1943 with the idea to seal the boxes with a fabric tape, which she had tested at her factory. The letter was forwarded to the War Production Board, who put Johnson & Johnson on the job.[12] Their new unnamed product was made of thin cotton duck tape coated in waterproof polyethylene (plastic) with a layer of rubber-based gray adhesive ("Polycoat") bonded to one side.[6][13][14][15][16][17] It was easy to apply and remove, and was soon adapted to repair military equipment quickly, including vehicles and weapons.[13] This tape, colored in army-standard matte olive drab, was nicknamed "duck tape" by the soldiers.[18] Various theories have been put forward for the nickname, including the descendant relation to cotton duck fabric, the waterproof characteristics of a duck bird, and even the 1942 amphibious military vehicle DUKW which was pronounced "duck".[19]"
So regardless of precisely
why it was called that, the "duck tape" usage precedes any application as a sealant for "ducts" in HVAC systems.
Yeah, I was surprised too.
And no, duck tape isn't for ducks although I've heard it works well on gerbils.
And bloody zombie body parts.
