in the name of jesus: You know what? If you want to fight with me, go ahead but don't bring Taeyoung in here because he doesn't deserve your trash talk about him, okay? And the person who will die with a cancer might be you, not others.

A gadget the people can use in place of their own lack of common sense.

This item would prevent them from purchasing most garbage advertised on TV, especially those that offer a "second one absolutely free... just pay separate shipping and handling"

It would also keep people from making bizarre statements about loving mathematics, science, physics, etc., while proclaiming they have a disposition based in astrological pseudo-science.

It would also knock them onto their posterior for making arrogant statements about their ability and prowess vs. an entire other class of people like biology students, for example.
