Amazing things Not Yet Invented

This morning, sitting on the edge of my bed putting my shoes on, I heard the voice of my boyfriend, half-asleep from under the covers say,
"Someone should invent butt mints so that when you fart it smells minty and fresh. And it could work as an air deodorizer".
Setting aside for a moment the absurdity of the situation in which this was said, I have to admit that it's not a bad idea.
