Red and blue lights

Judi was sitting at the defendant table while the state trooper was being cross-examined on the witness stand.

The lawyer asked, “When you stopped Judi, were your red and blue lights flashing?”

“Yes, sir, they were.”

“Did the defendant say anything when she got out of her car?”

“Yes, sir, she did.”

“And,” looking at Judi, "what was it she said?”

“She said, ‘What disco am I at?’”
