Season 1, "Safe House"
"Shoot yourself into me, Clark!"
As a means of infiltrating the FBI, Philip routinely poses as "Clark Westerfeld," who, as he sells it, works for the Internal Affairs Division, overseeing counterintelligence agencies. As Clark, Philip is able to woo over Martha Hanson, the secretary of a top FBI supervisor. Poor, lovelorn Martha is a perfect target for the Jennings' operations, and her aggressive sexual exploits with Clark lend the show some much-needed levity.
Early in their courtship, Martha screams this infamous line -- "Shoot yourself into me, Clark!" -- during one of their many sweaty, aggressive sex scenes. It's as cringeworthy as it is hilarious. But every Clark and Martha moment is layered with a tinge of sadness; she thinks she's falling in love, and he knows he's culpable in her fantasies. Their complicated relationship becomes one of The Americans’ more touching side stories.
