Captain Trunk

Captain T
Hammer and Doreau are supervised by the chronically uptight, Pepto-Bismol-guzzling Captain Trunk. Trunk spends most of his time yelling at Hammer for his incompetence or complaining about his migraine headaches brought on by Hammer's antics. Trunk remembers the day Hammer joined the force as the worst day in his life. Just like Hammer, Trunk is divorced.
