These are the Easter eggs you can find in "60 Seconds!"
Terry Pratchett/Discworld Edit
One of the relative photos that you find in the boy scout book involves "Uncle Terry" who told stories about "Turtles, elephants and wizards" This is a reference to the Discworld novels written by Terry Pratchett, where the world, shaped like a flat disc, is being held up by four giant elephants and one giant turtle swimming through space.

A character encountered when out exploring is running a convenience store that has its windows boarded up and a sign that says "We assure you we are open". A reference to the Kevin Smith film "Clerks". In which Dante has to create such a sign when the shutters are sabotaged by having chewing gum stuffed into the lock. (This was actually to get around the fact that film was shot in the store at night when the shutters were closed.)
Indiana Jones Edit
There is also a similar reference with Mary Jane, Where if she is left behind and she comes back barely alive, She will claim that she hid in a refrigerator to survive the nuclear Explosion, which is also a reference to the said scene.
Fallout 1 Edit
A stranger may knock on the door of your shelter asking if you could trade him a "Water Chip". This is in reference to the post-apocalyptic game Fallout 1; where the protagonist is sent into the wasteland to find a replacement for their vault's broken water chip.
Sometimes, you may find some markings on your map that were "not original" and you will have the option to send a family member out to investigate. If you choose not to, a message may appear in the journal the next day making fun of the thought of checking it out and stating "What would be buried there, if anything at all? Half a dozen bottle caps?" This is a reference to caps, the valuable main currency in the Fallout games.
Fallout 3 EditDuring a scavenging mission you might run across a church that has been partially destroyed by an un-exploded bomb. Survivors have begun to worship the bomb. This references the church called "Children of Atom" in Megaton.
Sometimes, if you listen to the radio before ending the day, the day after it will reference the song, "I don't want to set the world on fire". This song played in the very beginning of Fallout 3. The text says something like, "We spent all night singing about setting the world on fire" (or something on those lines, need reference, and a picture would be great).
After few days in the shelter, on the wall appears the picture of a two-headed cow. This is a reference to Brahmins, cows in Fallout with two heads and over-sized udders.
Another Easter egg is an event with a trader. A female trader will show up with a grumpy mercenary who acts as her body guard. She also gives useless survival tips. This is a reference to a trader in Megaton, Moira Brown.
Another possible easter egg is when Dolores leaves the shelter after going insane for a prolonged period of time.

This is a reference to Star Wars: Episode 5, where Luke's hand gets cut off by Darth Vader.
