The Game of Destruction

I allow the stunned yeti-thrower to die at the hands of a giant insect-breathing reanimated mummy.

I kill the mummy by using a bomb to destroy the ground under it causing it to fall into lava.

(The object is the lava since the bomb was destroyed)

I dig into the bottom of the lava pit with a mattock, causing it to vaporize.  The lava, that is.

(Also, the bomb would have killed the mummy in the first place.)

i hit a fuel tank with the mattock, the tank exploded destroing the mattock and i jump out from the explosion in slow-mo while dogding a shoe
(Object:shoe)

>kill shoe
  What do you want to kill the Shoe with?
>everything
  You take a swing at Shoe with Everything.
  Shoe is dead!

Object: Everything

I kill Everything. With fire!
(Fire is the object)

I use a fire extinguisher to put out the fire.  But it's one of those crappy fire extinguishers that doesn't work, so I don't actually spray it at the fire; I just throw it into the fire, causing it to explode in a shower of fairly toxic fire-extinguishment crap.  It may or may not contain CO2, water, or kittens, but it puts out the fire, leaving nothing but a mound of unbreathable cold sludge and ash.

I "accidentally" use a club to knock the fire extinguisher off a cliff.

*rains a giant golf ball on to the club to mash the club into basic putty*
The golf ball wanted revenge, so it got its wish.   

I drop a train on your golf ball, smashing it into the ground. 

*pulls out a bolt from the tracks and sends the train to its doom*
(object is the bolt)

I summon a bolt of lightning to fry your bolt. Pun is fun, hurr durr durp.
(The lightning is the object, try to destroy that!)

I divide by zero. There is no lightning.

*tinkers with the calculator to become a ternary calculator*  (For those who are oblivious to ternary, pull your hand out and count yer knucklebone.  Easy way to remember powers of 3.  )
With ternary, there is NO zero, so dividing by zero can NOT occur!  *cackles evilly as his new device of ternary calculator is up on the sacrificial altar*

*uses a hammer to destoy the calculator
