The bottom of Michael's chart about Eleanor reads "Page 4,815 of 162,342", a nod to The Numbers (4, 8, 15, 16, 23, 42) commonly featured in Lost (2004).
When Eleanor is reading the definition of determinism she is reading from a book named 'Philosophy for Dingdongs ... for Morons.'
The message on Michael's waiting room wall frequently changes between the reboots. The original read: "Welcome! Everything is fine", but after the first reboot it read "Welcome! Everything is Great!" Michael seems to have later decided to reverse the progression of enthusiasm and one of the reboots shown in this episode has it changed to just "Welcome! Everything is okay."
Tahani is always mentioning famous people she knows. This time she mentions Barbara Streisand.
