Son of... Whatever

I like Quark, and "The House of Quark" (3x03) is a good episode for him.

Quark takes credit for killing a Klingon who tried to kill him, but the Klingon was so drunk he ended up falling on his own knife. The story of the heroic Quark killing the Klingon brings more business to his bar, but the story comes back to get him in some trouble. Not surprisingly, he ends up having to face a Klingon in hand-to-hand combat after basically accusing him of scheming and plotting... like a Ferengi.

I love the what-the-fuck expressions on the Klingon's faces and how Gowron gives his PADD a subtle toss. Later, when Quark decides to go face D'Ghor, he makes a great introduction.
