A Pun Hiding in Plain Sight (S5E8)

When Captain Picard finds Ambassador Spock on Romulus, he attempts to talk him into returning home before their next meal. Spock demurs, and instead chooses to visit a ramen place everyone's raving about. Meanwhile, Commander Riker goes to a karaoke bar with Worf, whose interpretation of an opera song is not a hit with the audience. Do Trekkers have to choose between "Old Testament Rod" or "New Testament Rod"? What is an HHHHJ? It's the episode where Adam messes up his audio!
