Trivia: While Buzz is riding RC chasing after the moving truck, when Scud runs into the intersection causing the car pile-up, we see the building "Virtual Realty" the real estate company that sold Andy's house, and the bowling alley "Luxo Lanes" named after "Luxo, Jr" the first short film produced by Pixar in 1986. In the car pile-up, a blue car's license plate is "RES1536" which is also the Pizza Planet truck's license plate number, and the number's taken from Toy Story's film resolution - 1536 x 922, the RES stands for resolution. Also, on the teal car's tire it reads "Tigger Paw" named after Disney's Tigger, and a play on the brand Uniroyal Tiger Paw tires.
Trivia: The sound the globe makes when rolling towards Buzz is the exact same noise as the boulder that rolls toward Indiana Jones in Raiders of the Lost Ark. (00:27:10)
Trivia: In Andy's room, when Buzz Lightyear tries to prove to everyone that he can fly, he bounces off the ball (red star/blue stripe) from Pixar's first film, Luxo Jr.
Trivia: There's a hidden Mickey on the 'MEGADORK' poster in Sid's room - the Mickey tattoo on the musician's arm.
Trivia: The moving company, "Eggman Movers", is named after art director Ralph Eggleston. (01:08:30)
Trivia: When Woody accidentally wakes up Sid's dog, its growl is that of the T. Rex from Jurassic Park.
Trivia: One of the books on Andy's bookshelf is "Smyrl, Smyrl, Twist and Twirl". This is a reference to Eliot Smryl on the modeling team.
Answer: There wasn't anything for him to get drunk on. He was just wallowing in self pity and frankly, his world had just fallen apart, so it's understandable that he'd act a little loopy as a reaction.
