When Frank (Kevin Spacey) meets with Hammerschmidt (Boris McGiver) regarding the article alleging Frank's involvement in Zoe's death, Frank asks, "Why don't you just ask when I stopped strangling people's pets?" In the opening scene of the very first episode, we see Frank do just that.
Rachael Price, who sang the National Anthem at the baseball game, is the lead singer of the band Lake Street Dive.
Unlike what Rachel said, biblical Rachel married Jacob after he had worked 14 years for her father (after the first 7 he married her older sister and continued working 7 more to marry Rachel). Also Benjamin was Rachel's son too. Josef, her elder son didn't become a king, but the Egyptian king's advisor.
