First sighting of Abby's Caf-Pow.
Chad W. Murray, who plays the dead sailor, is the younger brother of Sean Murray, who later joined the series as Timothy McGee.
The ship shown in this episode is the USS Arleigh Burke DDG-51 (Guided Missile Destroyer) first of her class. Named after Admiral Arleigh Burke. Her motto is "Fast and Feared".
One of the seamen asks DiNozzo if he is a fan of pirate movies, to which DiNozzo replies "No." Later on in the series, it is established that Tony is a film buff, and is a fan of the Pirates of the Caribbean movies. As such DiNozzo was likely saying No just to irritate the seaman
As Abby works to crack the video game, Caf-Pows accumulate on her desk. There is a close-up of the first when Ducky comes in, interested in the game. He leaves, but returns with a second one, for which she thanks him, calling him a "prince". Both drinks have orange straws. Later when Abby comes to a password prompt, still two Caf-Pows are visible, but one straw is now green. She mutters the password cracking software could take a while. When the code breaker hits later on, Abby is dozing with now four Caf-Pows on her desk, three with orange straws and one green.
