Who's Ringabell?

I was in the Living Room while Brecken and Russ were in the kitchen and I overheard the following conversation :

After trying to jog Brecken's memory of who somebody was...

Russ: Does that ring a bell?

Brecken: Who's Ringabell?

Russ: No, ring a bell isn't a person, it's a saying.

Brecken: But who is Ringabell?

Russ: No, it means to remember. When I say "Does that ring a bell?" that means "Do you remember?"

Brecken: I don't remember Ringabell.

Russ: No, honey, ring a bell isn't a person. It means to remember.

Brecken: Oooooooh! I get it! Ringabell isn't a person. She's just pretend!

I'm pretty sure she didn't get it, but in her defense: Annabell, Isabell, Ringabell... I see her logic :)
