I don't understand

[Morphing_Dwarf]

Why is it that we can have giant station-wide explosions that remove our butts, but can't have poo? Not asking for poo, just for the removal of the butt thing.. There have been many times when I am the middle of doing something important things such as killing, arresting, healing, and other tasks best done uninterrupted, when I am knocked down and stunned... It doesn't make much sense to me, please explain.
