My three year old daughter saw the Wall-E billboard on the Xbox and said, "I want to play the Wall-E and Eva game." I tried to convince her that it probably wasn't very good, as it's a movie license game and movie license games are rarely good, but she was insistent. And when we downloaded it and it didn't run (there's some problem with my Xbox hard-drive; other games/demos had the same issue - it's funny when the sidebar comes out that suggests I wipe the disk with a soft cloth) she seemed accepting at first but then, a couple days later, repeated, "I want to play the Wall-E and Eva game."
Three years old! We get 'em young.
