I steal the pogo stick and modify it so I can never fall off HaHaHaHaHaah!
I have the incredibly long named slingshot that does an insane amount of damage to level 35 paladins from the planet Yeunerin, and also owns at target practice.
I have a weapon just like my last one except that it cannot be modified by anybody to make it so that anybody besides myself can ride it without falling off.
So many people fall off, the army comes in, quarrantines you and the pogo stick in different rooms, and forces you to pay the medical bills the pogo stick caused.
oh god I thinnk you beat me to making the ultimate weapon :O
it has one flaw though... I mute it >
solution A: ok I have the same weapon as last time except that I (and only I) can use it to teleport to any location that I wish (and yes, I have control over when I teleport and where I teleport). I can use this feature to avoid the military and continue work on the pogo stick of doom.
Solution B: Same weapon as before except that this time it is so irresistable that everybody in the army rides it and falls off. I escape and take the pogo stick with me. (I, of course, can resist the pogo stick's irresistability)
