Henry Winkler, who plays Barry the lawyer, is shown near the end of the episode looking into a mirror about to comb his hair and does a "Hey" sort of shrug. Henry played "Fonzie" back in the 70s/80s who was a greaser who combed his hair and did the "Eyyyy" catchphrase.
In the "Next Time on..." segment there is a Bluth Cornballer sitting in a corner of Maggie (Julia Louis-Dreyfus)'s kitchen.
Even before this episode, posters reading "Save Surely" can be seen on the walls when George-Michael (Michael Cera) and Maeby (Alia Shawkat) are at school.
