The State Trooper Testifies

During a trial against a drunk driver, a State Trooper was questioned by the prosecution.
"When you stopped the defendant, were the red and blue lights on your cruiser flashing?" the lawyer asks.
"Yes, sir," responds the Trooper.
"Did the defendant say anything when she stumbled out of her car?"
"Yes, sir."
"What did she say?"
The Trooper answers, "What disco am I at?"
