This episode does not follow continuity. It was a one-off special episode for the Olympics on NBC, which is why Cheyenne is still pregnant.
The female Cloud 9 customer who tries on a black jacket is McKayla Maroney, American former artistic gymnast, famous for her "not impressed" facial expression. Her expression became an Internet meme and she recreates it in the show, acting like she is not impressed with the outfit. Maroney competed in the 2012 Olympics.
Multiple Olympic athletes are featured in this episode's transition scenes. Speed skater Apolo Ohno is customer trapped in an aisle by an old lady's cart. Figure skater Tara Lipinski is customer who "slips" and spins. Gymnast McKayla Maroney is the customer trying on a black jacket doing her infamous side smile.
