One of Steve's toys, in the scene where he spies on Stan, is Agathor, Steve's online RPG avatar from the episode Dungeons and Wagons (2006).
When Steve says "Dad you need to eat, your doing a reverse Vince Vaughn" the joke was originally supposed to be reverse Jason Segel but, MacFarlane who was friends with Segel refused to say it so they changed it to Vince Vaughn.
At the beginning when Steve says "To forever, and above!" This is a parody of the Buzz Lightyear phrase "to infinity and beyond!
When Stan and Steve are about to get kidnapped, Stan's car is parked in front of "La Almeja Borracha," which is Spanish for "The Drunken Clam," which is the name of the bar in Family Guy.
