Not a joke, for real.
They are experts at getting you to talk to them even if you know this. They are experts at getting you to say things that incriminate you or your friends -- that you or your friends have done nothing wrong (in your opinion/as far as you know) will not protect you.
The only answers you should be rehearsing or thinking of in advance are "I would like a lawyer" and "I would like to remain silent." They are rehearsing how to get you to say incriminating things, a lot. Rehearsing or thinking up any other answers only plays into their strengths. Even knowing this, I've been tricked into talking to them, to my detriment. They are really good at it.
