Happy Endings - Season 2 Episode 7 -

Max gets a surprise visit from his pre-gay-awareness high-school girlfriend Angie, but when Dave hits on her absurdly-jealously invokes the gays code, and when it's not observed, declares a pranking code war. Penny hides her jealousy by faking extreme fondness of Angie, while Alex simply gets a straight crush on Max. Brad's innocently flirtatious 'work wife' gets Jane jealous enough to hit on an innocent HR cutie.
