"Did you use my camera?"

"No."

"Did you touch it at all today?"

"No."

"Then why is there a picture of the lens cap from an hour ago?"

"Oh yeah. I was zooming in and out on it."

"Yeah? Did you drop it?"

"No."

"Are you sure?"

"YES. I didn't do anything to it."

"Well, that's funny, because it was working perfectly fine the last time *I* used it, and now, since YOU'VE used it, it's broken."

"It can't be broken."

"IT'S BROKEN. THE SHUTTER MIRROR IS OBVIOUSLY BROKEN."

"Is that bad?"

"YES. THAT IS BAD."

"Well, I didn't do it."
