Monty says that he delivered Luke fifteen years ago. It would mean that Luke is fifteen, but he is actually sixteen since his sixteenth birthday was mentioned in season 6 episode "Three Turkeys" which took place before this episode.
Because this episode would air on April Fool's Day, it was filmed with a few pranks for the audience. The title sequence uses the family pictures from season 1. Also the painting of leaning legs in Jay's and Gloria's entryway changes its shoes from sneakers to dance shoes to fuzzy slippers when it usually appears with sandals.
The songs 4-16 listed in Claire's "Top 25 Most Played" playlist in iTunes are: Fix You by Coldplay, Thunder Road by Bruce Springsteen, Bad Romance by Lady GaGa, Gravity by John Mayer, Just the Way You Are by Bruno Mars, Cherry Pie by Warrant, Single Ladies by Beyonce, Caroline I See You by James Taylor, Return to Pooh Corner by Kenny Loggins, Fireball by Pitbull, Moonlight by Bob Dylan, Break Ya Neck by Busta Rhymes, and I'm Your Baby Tonight by Whitney Houston
Claire sitting next to a drunken passenger in this episode is a direct reference to a real life experience of Ryan Case, one of the editors of Modern Family. Case tweeted the entire incident as it was happening and it went viral. You can read the stream of her 64 tweets here http://goo.gl/tF4GeR
When did Claire get over her fear of flying? In "Airport 2010" from season one, Claire was so panicked that she had to get drunk to the point of Phil needing to carry her onto the plane. In this episode she can't wait to board the plane, remains sober, and seems very relaxed in the air (even when Phil fakes the turbulence).
Pepper says that one of his reasons to adopt Sal's baby is that he has always wanted a child. But throughout the series Pepper has repeatedly mentioned that he has a son, Kyle, who is a Navy SEAL.
Why is Mitch so off balance on his skates and unable to execute a simple change of direction at the fork in the tunnel? It is well established in Mofy canon that Mitch was a talented ice dancer as a kid; and in the season 4 episode My Hero at the roller rink, Mitch had no problems being on his skates. He should have been able to turn around with ease.
There is a continuity error. Claire brags that for last year's Halloween she pulled off a stunt so scary that it hospitalized someone. This would be the incident of answering the door and pulling a fake bleeding heart from her chest. But in order of the show's episodes, this incident must have happened 3 years ago since in season 4 Claire dresses like Little Bo Peep in a kid friendly attempt at Halloween because of her almost scaring someone to death the year before.
This is the first episode of the series not to have a credits scene. Instead, an extended version of the theme song is played during the credits.
Haley's photo of Claire staring at Gloria's breasts is a recreation of the infamous photo of Sophia Loren and Jayne Mansfield, where Loren stares at Mansfield's cleavage in a low-cut dress.
The football game watched by Jay and Phil at parents' night was old footage of a Canadian Football League (CFL) game between the Toronto Argonauts in dark blue jerseys and the Montreal Alouettes in white with red and blue trim.
The title Suddenly Last Summer refers to the events of the summer of 2013 when California approved gay marriage laws.
The cutaway involving Phil, Claire and the alpaca is a continuation of a flashback cutaway from the Season 3 episode, "After the Fire."
Continuity error: While Claire and Cameron are each trying to get Pam to support their position regarding a backyard water feature, Claire first had her arms crossed, suddenly was holding a water bottle, then had her arms crossed again, and then picked up the bottle.
Towards the end, when Phil gets a call from Claire and gets scared, the camera moves so that a picture of a skull hanging on the wall behind him can be seen. The picture is actually Charles Allan Gilbert's painting All is Vanity, which shows a woman sitting in front of a vanity-mirror, but from a distance looks like a skull.
After Phil (Ty Burrell) is seen running away from his doctor's office after being terrified from having an "operation", he passes a bus-stop bench that has an advertisement that reads "NOT JUST ANOTHER REALTOR, A MAN WHO CARES!" with his image as a Realtor on it. When he sits down on the bench, he's blocking most of the add until it reads "NOT A REAL MAN", alluding to the fact he was going to have a vasectomy.
In the end tag scene when Luke is handing back Claire and Phil the mail, the following episodes are referenced: "Dude Ranch," "Disneyland," "Treehouse," and "Virgin Territory" (twice!!)
The sporty black convertible that plays a feature role in the episode storyline is an iconic Porsche in spite of having its famous badges removed from the front rear and interior. It is always referred to by generic terms even when it seems awkward to do so. In contrast, Andre mentions Phil getting his usual Cadillac lease at the start of the episode.
Ellen Barkin (Mitzy Roth) goes on to play a real estate agent in The New Normal too.
We find out that Cam's birth date is 02/29/1972 and that his favourite movie is The Wizard of Oz.
