step 1- stop time (or at least slow it down enough that there's no appreciable difference)
step 2- slap the hostage takers
step 3- restart time
step 4- laugh as the hostage taker's heads explode from being hit at nearly the speed of light
Have you ever laughed so hard you started coughing?
And wouldn't the hostage taker's head just become a red smear on the wall, instead of explode?
ENIWAY
I would use my bag-o-infinity to create microscopic bears with chainsaws, and tell them to acumulate in their brains until I tell them to attack, at which point the hostage taker's brains would turn into a fine pink mist that would jet out their ears.
I would invoke friendly graboids. (obscure movie reference FTW)
I would make no friendly fire a law of nature, and destroy the house with the BFG 9000/insert badass weapon here
