Improvising

If you don't have scissors you can fold paper and rip it against a corner of a table.

If you don't have a screwdriver you can use a dime or a piece of metal.

If you don't have a flashlight you can redirect light with a mirror.

If you are MacGyver ;-) and need to plug a leak, you can use chewing gum. Didn't he always seem to have chewing gum?

If you don't have another car fuse you can use aluminum foil (don't try this at home).

If you don't have a Q-Tip, what in the world can you use? There just doesn't seem to be a replacement for a Q-Tip in a wet ear!

I'm just sayin'
