When Woody and Buzz are on the podium to present the Academy Award for best short animated film, watch what happens after Woody tells Buzz that he's supposed to be dressed up. Buzz presses a button and out springs a red bow tie that says "Happy 1972". The joke lies in the fact that the animators of Toy Story use Unix and/or Linux on their animation computers. Unix and/or Linux, unlike most operation systems doesn't add seconds from 1900, it adds seconds to the year 1972!
