Many of Nixon's quotes refer to his appearances in Futurama.
Nixon's CIA data system password is Checkers, a reference to his dog. He also refers to Checkers in some of his quotes.
There is a small photo of him in Kino der Toten. It is found on a table in the Pentagon room when the player teleports out of the Pack-a-Punch room.
Nixon is heard in an Easter Egg in Ascension, along with Fidel Castro and John F. Kennedy.
An Intel memorandum was forwarded to at-the-time Vice President Nixon, containing a dossier of Alex Mason.
Some of Nixon's quotes reference the Watergate scandal. This is odd since Five takes place in 1963, Nixon didn't become President until 1969, and the Watergate investigation began in 1972. Then again, the quotes are meant to be funny, so this fact is negated.
