There are a few references to "Dancing with the Stars." Gilles Marini was on season 8 and season 15 and almost won season 8.
Instead of the regular music during the Switched At Birth credit, the sound of a record playing is heard.
Both Gilles Marini and Marlee Matlin appeared on Dancing with the Stars. Marlee Matlin season 6 & Gilles Marini seasons 8 & 15.
