House waking up in the neighbors' kid's bed after a drunk night is likely inspired by the arrest of actor Robert Downey Jr. in 1996 for the same reason.
At the karaoke night, the song House, Foreman, and Chase sing is Midnight Train to Georgia by Gladys Knight and the Pips (with House and Foreman acting as Chase's Pips).
This episode sees House, Foreman and Chase doing karaoke together. Jesse Spencer (Chase) and Hugh Laurie (House) are in "Band From TV" together, in which they both sing, Laurie plays keyboard and Spencer plays violin.
