NASA finally surrendered to reality and hired the maximum expert on Earth about duck-taping tech, Japanese firm Nintendo, to take man on Mars.
They'll use their long-tested, effective, reliable and affordable tech, to duck-tape together as many rockets as needed to achieve the ambitious goal of driving the featherless biped to the red planet.
Here we can see the photographic proof, keeping together the three rockets of the prototype we can clearly distinguish the classic Ninty white duck-tape in a very unusual size:

Once I thought it was just a common misspelling, adopted for humourous purpose too and also eventually become a brand name, but I just found that "duck tape" is also a correct name for it, coming from a particular cotton cloth initially used to produce it.

Obviously I still prefer its use as intentional misspelling.   

Duck tape is just a brand of duct tape. ^_-

A joke needs the funny, and I don't see the funny.

That's what I understand as well. It's like calling all videogame consoles "Nintendo" or "Playstation."

Oh yeah... I remember when I was a kid, adults would call just any console a Nintendo, and every games a cartridge even when they started being on discs. xD

What is there to get? It's duct tape. It isn't rocket science.

bwa hahahahaha , well guys tell what the joke is?

Just realised that naughty Ninty ducktaped those rockets into a quite phallic spacecraft.
