Psych, Season 1

Gus:
Look! They call her the "School Marm Murderer."

Shawn:
OK, first of all, there's a question-mark at the end of that. They call her the "School Marm MURDERER?" Even the news people aren't convinced. And today at the courthouse, in the middle of the conversation, I saw her bend over, and picked up a piece of trash!

Gus:
Oh I see, so she picked up somebody's Kit-Kat wrap-up means she didn't kill anybody? That makes sense.
