Archer calls Cyril Alexander Miles. He received a patent for elevator doors that automatically open and shut.
When Krieger goes to his office to shut down the valets in the tubes (assumed to be either clones or robots), they are all made in Woodhouse's image, but at different ages.
On Archer's bookcase in his new office is a statue of a muffin. This is a reference to earlier episodes when Archer puts a muffin in a briefcase in lieu of money or bearer bonds to fool a villain.
After escaping from the elevator, Archer pours himself a glass of Glengoolie Blue - a completely fictional Scotch Whisky.
