Jake talks about having an app on his phone that makes him sound like T-Pain. Andy Samberg actually did a song with T-Pain as The Lonely Island, called "I'm on a Boat".
Gina suggests renaming Amy as Vanessa. Vanessa is Chelsea Peretti's middle name.
Gina says she will, "She's All That" Amy, to which Amy replies that she "didn't read that one." She's All That (1999) is a modern-day (at the time of its release) adaptation of George Bernard Shaw's "Pygmalion." Given Amy's penchant for intellectualism, she would likely have been familiar with the source material had Gina known of the connection.
