Easter egg: In the two-disc deluxe version, go to the root menu, highlight the first item; press the right navigation arrow and the knob on the TV highlights. Press enter to watch the Buzz Light Year TV commercial from the movie.
Easter egg: Go to "index" and select the star in the lower left hand corner (I think) this takes you to a screen that has a lot of titles on it. Press "play all" they are little movies like happy meal toys of Buzz Hamm Woody and Rex. They are also in stars all over the DVD (special edition disk 2).
Answer: This is a Disney/Pixar production, at no point are they intimating that kind of a relationship between son and father. If anything, the father simply doesn't care what his son gets up to so long as he isn't disturbed by it. Any other inferences you get from the movie are for you to contend with, but the family nature of the movie would suggest beating/abuse is not the answer.
