This applies to any situation which can be solved by the improbable application of:
1) a swiss army knife
2) a roll of duct tape
3) a match
4) Richard Dean Anderson (aka MacGuyver)
MacGuyver i don't know how you did it! Making a nuclear bomb out of that empty can of catfood was shear genius...
Rigging something moderately important and seemingly complicated in a pinch with a few simple items on hand......
Usually to complete a in progress task that otherwise couldn't be completed at that time.
The fuse to the starter relay blew out on the boat so Peckahead MacGyver'd-it by pulling out the burnt fuse wrapping it in aluminum foil and re inserting it to complete the circuit and the start the boat.
