You frantically scrounge around your undies for a weapon.

    Some crushed ice...

    Moldy lettuce...

    Plastic spoon...

    Not much to work with here.

    Wrap the ice in the moldy lettuce and use the spoon to fling it at you.

    Eat the lettuce as your last meal on Earth.

    Somehow combine these three common household objects into a bomb, MacGuyver-style.
