after a show in which (on an unrelated note) Ben and Sasa played a mother and son who were obsessed with a comic book superhero named Black Man...

Ben: Kate, you have so many blue clothes!
Me: Yeah, I do.
Ben: Have you ever thought about dyeing your hair blue?
Me: Many times!
Ben: Why haven't you done it?
Me: It's really expensive to get all that bleach and toner and dye for hair that's as long as mine.
Ben: Oh, okay. And your hair's really thick too.
Me: Yeah.
Sasa: If you ever do it, just make sure you don't accidentally dye your hair purple instead. Because purple is really close to blue.
Ben: ...Why would it be a bad thing if her hair turned out purple?
Me: Yeah, I wouldn't mind. I have a lot of purple clothes too.
Sasa: Oh. Okay. Well, I was just saying.
