I remember hitclips from looking around on that site. I had a cassette player though, until I got a cd player. And anybody else notice that the first toy story came out in 1995, and if you were born around 1992, you're going to college soon. They kinda have it so those who watched the first one as kids will have watched the third one as they're going to college.
And after clicking around on Wikipedia, apparently there is a pizza planet reference in every pixar movie but the incredibles. I didn't see one it toy story 3... but apparently it's there.
