The first part of the episode alludes to concussions in American football, a serious form of brain injury that has been widely associated with contact sports such as football.
After Kirk's hand injury, American former football player Joe Theismann is shown throwing up into his hat. Joe Theismann suffered a compound fracture of his leg in a Monday Night Football game, considered to be one of the worst and most horrifying injuries ever shown on live TV.
During the trip, they're listening to the song "You & Me & the Bottle Makes 3 Tonight (Baby)" by Big Bad Voodoo Daddy.
The song is heard one more time in the van and is later heard during the credits.
According to Kirk, the "craziest place" he has ever done it with Luann was at a Chipotle Mexican Grill restaurant.
On the van, the kids are watching classic lacrosse matches. Lisa praises an ankle-breaker performed by Gary Gait, the Canadian lacrosse player who is widely considered one of the greatest lacrosse players of all time.
Nelson mentions Gary's brother, Paul Gait, who is also considered one of the best lacrosse players of all time.
Kirk is dressed as and dances like the Blues Brothers in a music store, mirroring their iconic dance at Ray's Music Exchange in the 1980 comedy film The Blues Brothers.
The Godfather and Halo are mentioned in the chat Kirk had with Homer.
Kirk is dressed as one of the Blues Brothers and dances in a music store, mirroring their iconic dance at Ray's Music Exchange in the 1980 comedy film The Blues Brothers. On the website Kirk created, bluesbuddies.com:
"Celebrating the art of Jake and Elwood" refers to "Joliet" Jake (John Belushi) and Elwood Blues (Dan Aykroyd), the Blues Brothers.
A drunk Kirk says that "jet fuel can't melt steel". This is a reference to a famous conspiracy theory surrounding the September 11 attacks that claims that the planes alone would not have been able to bring down both towers.
The placement of some of the people at the town meeting changes between scenes.
There are 12 kids on the lacrosse team, but Field Lacrosse, the version being played in the episode, has a 10-player limit per team.
Furthermore, Apu's two children are not old enough to play either football or lacrosse.
Kirk is surprised by Homer being his friend, but they were already friends in some previous episodes, such as "The War of Art" and "A Milhouse Divided".
