During the last competition of the CampOlympics people chant "Steve boma ye!". This is a reference to the boxing match (called The Rumble In The Jungle) between George Foreman and Muhammad Alì in Kinshasa, Zaire (now Democratic Republic of the Congo) on October 30th 1974, when audience started to chant "Alì boma ye!" (Alì, kill him!)
Roger and Francine's role-playing as a married couple is essentially taken from the Edward Albee play Who's Afraid of Virginia Woolf.
This episode marks the first time that Roger gives one of his alter egos a complex backstory.
The song that plays both when Makeva first emerges from the water and when Stan and Steve are looking over their photograph of the campers is 'Africa' by TOTO. Appropriate, both from its title and lyrical content, involving falling in love in Africa, though none of the lyrics are heard in the episode.
The girl Steve meets and falls for is named Makeva. This is a reference to a character that Thandie Newton, who voiced Makeva, voiced earlier on the show ER, named Makemba Likasu, the love interest and later wife of Dr. John Carter, whom he met while in Africa.
