Grimm, Season 1

Nick:
You ever seen one of these? [Shows Monroe a drawing]

Monroe:
A Mauzhertz. Pretty favorable likeness actually, given the subject.

Nick:
Well, I think I saw one and he could be involved in a murder.

Monroe:
There's a reason you people never wrote about them. They never do anything worth writing about. This whole cartoon thing they got going, such a racket.

Nick:
So they're harmless?

Monroe:
Yeah. I mean you say "Boo" and they scurry off to their safety zones. They're very predictable that way.

Nick:
What about a Lausenschlange?

Monroe:
Lausenschlange? You saw a snake dude and lived to tell about it? Let me tell you, what you don't want to do is leave a Lausenschlange alone with a Mauzhertz. That is a recipe for dessert.
