ARDMORE, OK—Saying he was "just really thirsty," Mayor Earl Moore apologized to his constituents Tuesday after drinking the entire 1.5-million-gallon water supply housed in the town's water tower.

"I apologize that my actions today have left all of you without water, and I will do everything in my power to make sure we have water tomorrow," a visibly bloated Moore told reporters. "I woke up in the middle of the night and my mouth was dry. I thought I just needed a sip of water, but I was obviously thirstier than that."

Responding to criticism that he deeply mismanaged city resources, Moore promised to drive to nearby Marietta next time.
