you walk in and see a tall male seeming to be singing loudly, he is just bashing a shoe, or a boot? Onto the patients' neck violently, while singing like everything is just going to go well

"Laa laa laa laaa~ I am the cure to humanity~~ ooo~~ lalalaaa~ my dear patient~ I'll save youuuu~~"

he is singing like he is singing inside a concert, but he sounds terrible, but as he keeps bashing the shoe onto the patients' neck, he doesn't seem to notice you

"Lalaa laaa!!~~"
