I sent my brother a package once that I taped up with duct tape. The next Christmas he sent me a joke book about the uses of duct tape.
I try to always have a roll of duct tape with me in my RV. I saw the rubber gasket coming out of the big window by the dinette one time and had to stop on the side of the road and duct tape it in so the window wouldn't fall out. Duct tape is handy stuff.
