#1 The toolbox that Sid places on top of the crate Woody hides in is labeled with "Binford Tools," which is the fictional company that Tim Allen worked for in Home Improvement.
#2 Depending on how old you were when you saw Toy Story 2, you may or may not have caught the Jurassic Park reference as Rex was trying to catch up to his buddies.
#3 When Molly is reading an issue of Tween Zine in Toy Story 3, Darla from Finding Nemo makes an appearance on the cover. I thought I'd never have to see her again. I was wrong.
#4 If you look closely at Buzz and Woody's feet, you'll notice that the animators even thought about how Andy's penmanship would improve as he got older.
#5 Unless there's some other person out there about the same age as Sid with the exact same faded t-shirt, then I think we can all safely assume that the garbage man in Toy Story 3 is Sid.
#6 One of the games at Pizza Planet is a reference to the movie Alien and the scene where the creature pops out of the astronaut's stomach. That's appropriate for kids. Sure.
#7 There's a quick flash of a Lightning McQueen toy from Cars in the Butterfly Room during Toy Story 3. That no one is playing with him is actually shocking.
#8 The company that Sid purchases his massive firework from is called "Ill Eagle Fireworks." Sound it out. You got it. There we go. So not only was Sid evil, but he was also breaking the law.
#9 The stitching in Woody's right arm is more noticeable in Toy Story 3 because his arm was repaired in the second film. Seriously, these animators don't miss a beat.
#10 It's pretty obvious that Sid is a little bit off since the carpets in his house are the same as the ones from the Overlook Hotel in The Shining.
#11 That's not the only Shining reference related to Sid. When he grows up and becomes a garbage man, the license plate on his truck is "RM237."
This is a nod to the freaky room from the film that still gives me nightmares.
#12 In Toy Story 3, when Woody is peering out of Andy's bedroom door, you can see where Andy marked the heights of Jesse, Rex, and Buzz.
#13 The man who restores Woody to pristine condition is Geri from the Pixar short Geri's Game. If you don't remember, it's the one where an old man plays chess by himself and I cry.
#14 This is also evident when he opens one of his drawers that is full of chess pieces, and now I'm full-on sobbing.
#15 The gas station where Woody and Buzz get left behind is the same company that shows up in Cars as a major sponsor.
#16 The book that Rex is reading in Toy Story 2 has the U.S. price listed as $4.95 and $50.00 in Canadian dollars.
#17 In Monsters, Inc., when Boo brings Sully into her bedroom, you can see Jesse on the floor.
#18 The real estate company that is selling Andy's house is called Virtual Realty, and whoever came up with this brilliant name needs to be handed all of the awards immediately.
#19 Mrs. Potato Head appears to be reading a book about A Bug's Life during Toy Story 2.
#20 Apparently, A Bug's Life is a super popular movie throughout Toy Story 2 because in Al's Toy Barn, you can see some of the characters on the shelves as toys.
#21 At one point there's a glimpse of a postcard on Andy's bulletin board from Carl and Ellie, the couple from Up who broke our hearts five minutes into the movie.
#22 When Hamm is trying to find clues as to how to find Woody in Toy Story 2, he is literally standing on the board game Clue.
#23 Buy n Large, the brand of the batteries that power Buzz, is the same company from Wall-E that was behind putting all the humans on spaceships and sending robots to clean the earth.
#24 Finally, everyone's favorite Easter egg that flew over all of our innocent heads. Our minds were blown when we came to the realization that one of Sid's hybrid toys is...well, a literal hooker.
