I heard this several years ago, but it seems appropriate with the recent
Star Wars release:

Duct tape is like the Jedi Force. It has a light side, a dark side, and it
it can bind the universe together.

As a side note, my brother in law, who was involved with auto racing (his
dad worked for Champion) always referred to the stuff as "Racer's Tape"
since the drivers used it for quick repairs in the pit during the races.
