I got a 2 year old Nephew who I see almost every weekend, and while I love the kid to death, he insists on watching FINDING NEMO 20 times a day, so that's gotta be my least favorite right now.
Classic dialogue between my brother and Mom:
Brother: "Mom, what did I make you put on the VCR constantly when I was little?"
Mom: "We didn't have VCR's when you were little."
