There are thirty in total, I have picked three of my favourites.

10. Q: Trooper, when you stopped the defendant, were your red and
         blue lights flashing?
      A: Yes.
      Q: Did the defendant say anything when she got out of her car?
      A: Yes, sir.
      Q: What did she say?
      A: What disco am I at?

17. Q: You were there until the time you left, is that true?

30. Q: Doctor, before you performed the autopsy, did you check for a
         pulse?
      A: No.
      Q: Did you check for blood pressure?
      A: No.
      Q: Did you check for breathing?
      A: No.
      Q: So, then it is possible that the patient was alive when you
         began the autopsy?
      A: No.
      Q: How can you be so sure, Doctor?
      A: Because his brain was sitting on my desk in a jar.
      Q: But could the patient have still been alive never the less?
      A: It is possible that he could have been alive and practising law
         somewhere.
