Happy Endings Season 2 Episode 12

Jane convinces Penny to stop changing herself for every guy she dates, and instead to change the guy to suit her needs. Penny's first experiment is Jeff, a slacker who is 30 going on 20. Meanwhile, when Brad overhears Jane bragging to Penny about how she completely made him over after they met, he rebels, and starts walking, talking and dressing like his college-era self. And Alex and Max stage an "in-T-vention" to stop Dave from his obsession with v-necked T-shirts.
