Call in Troops?

I don't usually blog much on Saturdays, since I try and treat it as a Day of Mindfulness, spent in leisure, meditation, cooking (and today, baking), and occasionally catching up on work. I just read something, however, which gave me a good laugh and I thought it'd be a nice thing to share. Every week, our law school newspaper publishes a column of amusing faculty quotes from the previous week. My favorite of this week comes from Professor Larry Walker's Complex Civil Litigation class:

L. Walker: "So there's an injunction here. Now how do you enforce it? Come on, somebody. How do you enforce it? You. How would you enforce this injunction?"
Student, quietly: "Ah, troops?"
Walker: "I'm sorry... what?"
Student: "You call in the troops?"
Walker: "Did you say, 'call in the troops?'"
Student: "Yes."
Walker: "No."

Good guess, though.
