Quote: I look at a basketball laying on the ground, and it makes me think of something. Popcorn ball. How ’bout a spicy popcorn ball? That is how my mind is always working. — Guy Ramsay Fieri (1968-) American restaurateur, author, & television presenter

Comment: This quality most often references spicy food, but it is used here as a way of thinking about human traits. We can imagine a person who can spice up a conversation, has a sharp (but not acerbic) wit, or encourages interest in exciting topics.
