In the opening couch gag, while Homer is being electrocuted, the camera shows Springfield from a birds eye view. In the layout of Springfield a large number 4 is clearly visible. This is due to the gag having been created originally as a TV Ident for the UK TV channel 'Channel 4'. The channel 4 ident also predates the Simpsons episode by 7 years, The ident having aired in 2007, and the couch gag airing in 2014.
Marge's bedtime reading is 'Heaven Is Real' by Captain Nutso.
