Exactly what I need. If I'm ever captured and tortured, then set adrift on a burning raft, become stranded on a desert island only to be attacked by fire ants until I can build a defensable tree house, make fire and kill giant pigs for food, I will have everything I need right in my pocket. Of course, it may be too heavy to permit me to swim to shore so...

So THAT'S how McGyver did it!!!

That and knowing how to make a bomb out of fishing line and a piece of bubble gum.

What? All that and no bottle opener?
