During the dinner scene, Daniel and Johnny talk about the blueberry pie incident, which was actually a deleted scene from the original 1984 film.
Pulpo is the Spanish word for octopus, possibly referring to the stuffed octopus Sam won on her first date with Miguel in season 1, as she takes it out of a closet right before going to a party with Robby.
During the party scene, Stingray can been seen with two malt liquor bottles duct taped to his hands. This is a game called Edward 40 Hands, from How I Met Your Mother (2005), in which William Zabka (Johnny Lawrence) is featured in Season 8 and 9.
