So last night over drinks, I told Mark about the airhorn*-related antics that have occurred around the house over the last few weeks. Then Mark told me about some knife that has a CO2 cartridge attached to it - apparently designed so that when you stab someone, you can also press a button and the knife will expel CO2 into their bloodstream, blowing them the fuck up (maybe).
This led me to conclude that the ultimate knife would have an airhorn attached to it such that, when you stabbed someone, the airhorn would go off until the person had expired, thereby allowing you to avoid that constant horror-movie issue where you stab someone, they "die", you relax, and they stand up behind you and continue to terrorize you.
Anyways. If any of you are bored and interested in editing my posts so that they contain more than three sentences, you just let me know.
*every year, my dad gives each of us an airhorn at Christmas. He usually gets himself one as well, and uses it to terrorize my mother.
