While Andy (Chris Pratt) talks with April (Aubrey Plaza) about how things in London are different than they are in the United States, he mentions Piccadilly Circus and how he saw a bearded lady who "got all rude when I marveled at her." This is possibly a reference to the Jethro Tull song "Mother Goose." The lyrics include: "And the foreign student said to me, 'Is it really true, there are elephants, lions too, in Piccadilly Circus?'" And: "And the bearded lady said to me, if you start your raving, and your misbehaving, you'll be sorry."
