Первое пасхальное яйцо, которое я заметил, был кадр из эпизода "Road To Rupert", где на дворовой распродаже Брайан и Стьюи продают, среди прочего, DVD "Stewie Griffin: The Untold Story". Это было легко заметить, но в FG тьма "easter eggs". Вот, что я смог найти в интернете:

Music Men
In the episode, Brian Does Hollywood, near the end of the show Ron Jeremy is seen anouncing an award for the "Best original score in an adult film. The nominees are: Ron Jones, Walter Murphy and John Williams."
Ron Jones did the music for Family Guy.
And the Family Guy title music is by Walter Murphy.
John Williams conducting porn music...well that's just funny

Neil Goldman
The character Neil Goldman (red-haired nerdy admirer of Meg Griffin) is also the name of a writer on the family guy crew.

Gumble 2 Gumble
Watch the episode where people start worshiping peter because they think he is a god, peter tries to get his favourite show Gumble 2 Gumble back on the air, the egg in this is that Gumble 2 Gumble was the original show Seth McFarlane pitched to the fox network.

Family Guy - Peter's, Stewie's and Brian's Wife?
In the Family Guy episode "Fifteen Minutes of Shame", Meg has her friends over to her house for a slumber party. There is a girl who is at the party with short, blond, hair, and a blue hair clip. She is the animated version of Seth Macfarlane's (the voice actor of Peter, Stewie, and Brian) wife.
She is seen several times in the episode, first when she is with the entire group of girls while talking about boys, and a second time when she wakes up in the middle of the night to find Chris standing over her looking at her.
Enjoy!

Family Guy - Brown Vs. Board of Education
In the episode where Brian goes back to college at Brown, go to the scene at the football game. If you have a DVD player, pause the split second where it shows the scoreboard. If not, just pay attention closely. The scoreboard says "Brown: 42, Board of Education: 0".

Family Guy - Upside Down TV
I can't recall which episode it is in, but in a scene where peter is in some weird futuristic red/green car, he is racing another car. in the background, before he talks to the other driver, slow down your dvd. if you look at the writing on the back wall, it will say something along the lines of "if you can read this, your tv is upside down"

Family Guy - Luke Perry TV Guide
This is somewhat noticable but i still find it funny
if you dont have the dvd of family guy with the luke perry is gay episode then your going to need quick eyes
when peter is trying to think of "a much more interesting story" for megs story in the school paper he looks at the TV GUIDE
now if you have the dvd pause it when the TV Guide comes on
if not well watch closely
if you look in the bottom right corner of the TV Guide there will be a message that says
"If you can read this, Family Guy is on the air"
it might not be great but i still like it and hope you will too

Family Guy - Viewer Mail Butt Grab
In the 3 part show "Family Guy Viewer Mail #1", go to the episode "Super Griffins". This egg is hidden in the part where Mayor Adam West is giving a speech to the citizens of Quahog explaining that he will roll around in toxic waste and defeat the Griffins. When he leaves and the audience gives him a standup applause, look very closely at the right side of the audience. In this a black man grabs the butt of a woman standing next to him. This is highly unnoticable if you don't know about it and is very funny.

Family Guy - Hidden Newspaper Headline
In episode 410 "Model Misbehavior" The griffin win a boat race and they make the paper. When Lois holds up the paper to show that they were in it, here you should you pause the scene, and in the bottom right corner of the paper a headline reads. "DVDS PAUSED FOR HEADLINE JOKE -- MILLIONS DISSAPOINTED"
I thought this was pretty funny, i wasnt dissapointed AT ALL!

Family Guy - 'Stewie Griffin: The Untold Story' for sale
At the very starting scene of 'Road to Rupert', when Stewie asks Brian where his teddy bear is, you can see on the right a DVD titled the "Stewie Griffin: The Untold Story" which of course is the straight to DVD Family Guy movie.

Quagmire Pilot easter egg on FlightAware
FlightAware has a hilarious Family Guy easter egg when you try to track flight "QUAG1" (Quagmire)

Brian Goes To College
Когда Спец Бригада выигрывает приз за лучший костюм(в самом начале), камера переходит на проигравшую Спец Бригаду(та, кот. без чёрного парня) видно Тома Такера, который "исчезает". Вернее он скользит с экрана... Не знаю, если это яйцо, но меня это удивило

Занимательный материальчик

Luigi, думаю, это тоже вполне может быть пасхальным яйцом. Если бы это было обычным ляпом, он бы тупо исчез, а то он плавно и красиво отъезжает в сторону.
