After Jesse loses her cell phone after a night of drinking, she gets a new one that is completely different. But after she loses it her cell phone changes back and forth between the first one she lost and the new one she got afterwards.
When Jessie and Colin are talking about their mutual love of Joni Mitchell's music, they particularly praise "that stuff she did with Mingus." Joni Mitchell and jazz musician Charles Mingus were planning to make an album together and had written three songs for it, but Mingus died before they could actually record together. The "Mingus" album Mitchell eventually released was recorded after Mingus's death and featured the three songs they had written together, a fourth song in which Mitchell added lyrics to one of Mingus's older compositions, and two songs Mitchell wrote on her own after Mingus's death, one of which was about him.
