"He's a neck biter"

Tonight's moment of Zen:

JJ: So what other shows are you watching?
S: I've also been watching Dracula.
JJ: Oh, so you're that one person out there watching it.
S: Ha, ha. But yes, that's me.
JJ: You know that show's not gonna make it.
S: Possibly not, but I hope it does. I like it. I mean, the plot is decent and . . . well, I enjoy it for other reasons, if you know what I mean . . .
JJ: Yes, I do.
S: Reasons I'd rather not discuss in front of your children.
J: Daddy, I know why. She likes Dracula 'cause he's a neck biter!
JJ: Yes, son. And because he bites other things, too.
S: Oh, boy.
