My wife, "Knuckles"

[I forgot to return a call from Laura and after a while she called me back. I stepped out onto the balcony to talk to her.]

Laura: I can't believe you forgot to call me back!
Jack: Yeah, I'm sorry. But you know... I was, um, just reaching into my pocket to get my cell phone when you called.
Laura: You're such a fibber! You better watch it: you're on a balcony so it would be really easy for God to strike you with lightning!
Jack: Okay, maybe I thought of calling you just after my phone rang...
Laura: It's a good thing my nickname isn't "Knuckles" or you would be in for quite a beating!
